You know that performance is crucial to your company's success, but do the people in the corner office know this? You need to get the message across using the language they speak and targeting the goals they care about.
This session -- presented by Strangeloop president Joshua Bixby at the 2011 Web Performance Summit -- summarizes the benefits of a faster website or web app, then delves into a series of how-tos for creating a business case for web performance in your organization.
London Web Performance Meetup: Performance for mortal companiesStrangeloop
You're probably familiar with the well-known performance success stories from companies like Amazon, Google, Microsoft and Shopzilla. But how relevant are these megasites to "mortal companies" that don't make billions of dollars per year or have teams of in-house performance engineers to do their bidding?
Strangeloop president Joshua Bixby walks through case studies of Strangeloop customers like AutoAnything.com and Artbeads.com to show how mortal companies have improved performance and achieved measurable success, including:
· Increased revenue by 13%
· Increased cart size by 6%
· Increased conversions by 9%
Joshua offers practical tips for successfully evangelizing performance within your organization. He also gives a snapshot of the current performance landscape in North America, as well as a sense of where the industry is headed.
RFC 7540 was ratified over 2 years ago and, today, all major browsers, servers, and CDNs support the next generation of HTTP. Just over a year ago, at Velocity, we discussed the protocol, looked at some real world implications of its deployment and use, and what realistic expectations we should have from its use. Now that adoption is ramped up and the protocol is being regularly used on the Internet, it's a good time to revisit the protocol and its deployment. Has it evolved? Have we learned anything? Are all the features providing the benefits we were expecting? What's next?In this session, we'll review protocol basics and try to answer some of these questions based on real-world use of it. We'll dig into the core features like interaction with TCP, server push, priorities and dependencies, and HPACK. We'll look at these features through the lens of experience and see if good practice patterns have emerged. We'll also review available tools and discuss what protocol enhancements are in the near and not-so-near horizon.

Systematic Load Testing of Web ApplicationsJürg Stuker
Talk held at the conference Coding Serbia in Novi Sad.
Performance of web applications is a crucial dissatisfier for users and thus an important quality criteria -- also used by Google to rank their result lists. As with other quality aspects, performance testing cannot be done at the end of a project but is an integral part of the development process.
The practice presentations submitted explains web performance testing along practical examples in order to better understand and judge cause and effect of behavior observed. Usually few causes have a disproportionate effect on bad performance. In addition, it is important to understand diverse load and test scenarios to optimize application behavior.
The presentation also introduces a methodology to systematically define and assess performance metrics of an application. The content is based on open source tools and the presentation includes live testing to illustrate the excellent cost benefit ratio of systematically white box testing of performance using an HTTP proxy.

Site Down: How to Triage Those First MinutesJohn Gamboa
You visit your site and you don’t see what you’re expecting; you see a white screen, a 404 or a 502 error. Your site is down, and you’re losing visitors, and potentially lots of money. How do you handle those first pivotal minutes to find out what’s going on? With the experience and tools of front-line web support, John will go through the steps required to figure why your site is down and how to fix it as quickly as possible.
Giving and introduction to the site speed topic and talking about the limiting factors of site-speed, how site-speed can me measured and monitored, how site-speed can be connected to business metrics and finally about typical site speed optimizations.

Web Performance in the Age of HTTP/2 - FEDay Conference, Guangzhou, China 19/...Holger Bartel
Web performance optimisation has been gaining ground and is slowly getting more of its deserved recognition. Now that we’ve learned to recognise this integral part of user experience and are approaching HTTP/2 as our new protocol of choice, some of our existing web performance best practices will turn into the new anti-patterns.

Metrics, metrics everywhere (but where the heck do you start?)Tammy Everts
You want a single, unicorn metric that magically sums up the user experience, business value, and numbers that DevOps cares about, but so far, you're just not getting it. So where do you start? In this talk at the 2015 Velocity conference in Santa Clara, Cliff Crocker and I walked through various metrics that answer performance questions from multiple perspectives -- from designer and DevOps to CRO and CEO.
Metrics, Metrics Everywhere (but where the heck do you start?)SOASTA
Not surprisingly, there’s no one-size-fits-all performance metric (though life would be simpler if there were). Different metrics will give you different critical insights into whether or not your pages are delivering the results you want — both from your end user’s perspective and ultimately from your organization’s perspective. Join Tammy Everts, and walk through various metrics that answer performance questions from multiple perspectives. You’ll walk away with a better understanding of your options, as well as a clear understanding of how to choose the right metric for the right audience.

2012 Annual State of the Union for Mobile Ecommerce Performance [Velocity EU]Strangeloop
On October 3 at Velocity EU, Strangeloop president Joshua Bixby unveiled the findings from the first study ever conducted of mobile performance over cellular networks.
In July and September 2012, Strangeloop conducted an industry first: a mobile performance survey of top ecommerce sites. The "2012 State of Mobile Ecommerce Performance" documents how Strangeloop tested top Alexa-ranked retail sites on a variety of mobile devices to find answers to questions like:
- How long does the median site take to load in mobile browsers?
- Which sites were fastest?
- Do some mobile OS/browsers/devices offer a consistently faster user experience than others?
- How much faster are pages served over LTE than over 3G?
- How do all of these findings compare to similar research conducted for desktop performance, published in Strangeloop’s annual Page Speed and Website Performance State of the Union reports?
The report is available for download at http://www.strangeloopnetworks.com/.

Cloud Performance: Guide to Tackling Cloud Latency [Cloud Connect - Chicago 2...Strangeloop
Performance matters. And in the cloud, performance matters more than ever—layers of complexity and third-party, shared environments separate users from applications. Services are elastic, which means you can have any SLA you want, as long as you're willing to design it yourself. And you can have a fast application, too—if you're willing to deal with the bill at the end of the month.
So how should you think about cloud performance? In this in-depth workshop on the performance of cloud computing, three cloud computing and Internet performance experts—Steve Riley (Riverbed, Amazon), Hooman Beheshti (Strangeloop, Radware) and Alistair Croll (Coradiant, CloudOps)—take you on a tour of the challenges on-demand computing poses to reliable, fast user experiences.
What you'll learn:
- The new models of delay, capacity, and uptime that on-demand computing requires
- What and how to measure when it comes to performance, and how to think about metrics
- Where delay happens across the cloud environment
- How shared computing and back-end contention affect user experience
- What the WAN and the Application Delivery Network mean in a cloudy compute model
- How to spread load and optimize application front-ends to speed up applications
Velocity 2012: The 90-Minute Mobile Optimization Life CycleStrangeloop
Strangeloop VP Technology Hooman Beheshti demonstrates – in real time – the impact of advanced mobile optimization techniques on another unsuspecting website.
Over the course of the workshop, witness the mobile optimization life cycle, from start to finish:
- Taking the “Before” shot: Choosing a guinea pig site and benchmarking its current performance, focusing on load time, start render time and round trips.
- Iterating through core best practices, including: Keep-Alive, Compression, Far Future Expiry, and Use a CDN.
- Applying a set of advanced, automated, mobile-specific FEO techniques.
- Taking the “After” shot: Analyzing results using different browsers.
Marrying CDNs with Front-End Optimization Strangeloop
Slide deck from Strangeloop president Joshua Bixby's presentation at the 2012 Content Delivery Summit.
Many content owners are already using a content delivery network (CDN) to cache content closer to their visitors, but CDNs don't reduce the number of requests required to render each page, and they have no impact on browser efficiency. Front-end optimization (FEO) picks up where CDNs leave off, transforming the content itself so that it renders as quickly as possible in the browser.
In this presentation, attendees will see real-world examples of how leading e-commerce sites have combined CDN and FEO forces to reach new levels of performance for content-rich pages. Get real numbers on how quickly content-rich sites loaded pre-acceleration, then with just a CDN, then with a combined CDN/FEO solution.
Front End Optimization [Cloud Connect 2012]Strangeloop
From Hooman's presentation at the Cloud Performance Summit at Cloud Connect 2012:
Accelerating applications can mean different things to different people. In web applications, performance is impacted by everything from infrastructure to code to back-end processing to browser capabilities. This can get even more complicated in cloud environments. In this discussion, we'll focus on the issues surrounding the "front-end" performance of the application which includes all interactions between the browser and the app after the dynamic content (the base HTML) has been generated and delivered to the browser. We will discuss the major front-end performance pain points and some strategies for mitigating them (including hidden complications and gotchas), ultimately leading to a better perceived user experience.
Velocity 2010: Performance Impact, Part Two: More Findings from the Front Lin...Strangeloop
Last year at Velocity, Strangeloop's VP Product, Hooman Beheshti, presented the findings from phase one of Strangeloop’s long-term research into the relationship between web performance and business benefits. The results were also published in Watching Websites. Since then, we’ve received a barrage of questions from the web performance community, which fueled phase two of our study. In this presentation, Strangeloop president Joshua Bixby offers our most recent findings.
Some of the community’s questions were:
* Who were the clients?
* How fast were the pages?
* What acceleration techniques were implemented?
* What happened to the key page components (such as JS size, payload and roundtrips) of the websites?
* How did changing key variables (page load time, payload, number of roundtrips, etc.) affect the outcome?
We’ve been collecting and analyzing data to help us answer these questions, as well as some new ones we’ve thought up along the way. Join us as we present our findings, and help us consider what areas deserve further study.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
34. A Few Points of Clarification We’ll use it to describe where performance pain points are, but that doesn’t mean the page actually has these problems What we’re going to do: Improve performance incrementally Not so good (slow) Awesome (fast) * The real Velocity site is somewhere in the middle!
51. Performance Problems Too many connections (too much orange) Too many bytes (too much blue) Concurrency Bad Caching for repeat views No CDN (the greens are too big)
52. The Green Problem #1: No CDN TTFB
53. Performance Problems Too many connections (too much orange) Too many bytes (too much blue) Concurrency Bad Caching for repeat views No CDN (the greens are too big) Too Many Roundtrips (too many greens)
54. The Green Problem #2: Roundtrips Repeat View First View 80 Requests 78 Requests 27 Requests 14 Requests
55. The Green Problem #2: Roundtrips Every fetch still pays the HTTP overhead penalty TTFB is still a problem Exacerbated by concurrency issues Getting worse as number of objects per page grows Generally, the hardest problem to solve
56. Performance Problems Too many connections Too many bytes (too much blue) Concurrency Bad Caching for repeat views No CDN (the greens are too big) Too Many Roundtrips (too many greens) Others
57. Examples of Other Problems Blocking Javascript 3rd party calls (http://stevesouders.com/p3pc/)
58. Before and after: Keep-alives & compression http://www.youtube.com/watch?v=KPYBF41yiFw
64. Stepwise Acceleration Start from the beginning and fix the easy stuff Step by step acceleration of the page Apply techniques/methods/etc and see the result Try to make it as fast as possible
66. Keep-Alive Solves the too-many connection problem (Less Orange!) Will help alleviate the TCP connection setup overhead 97 Connections
67. Compression Addresses the too-many-bytes problem (Less Blue!) We’ll compress textual content (html/css/etc) Not the only solution to less blue, but the easiest
72. How Did We Do? Original KA+Comp Improvement First View Repeat View 52% 71% 34% 94% 31% 51% 23% 75% 40% 62%
73.
74. Pros and Cons Pros Really easy to do Single configuration switches in servers, proxies, or load balancers Good benefit seen right away Cons Compression has processing overhead On their own they’re just not enough
78. How Do We Get Better Caching RFC 2616, Section 13 Caching headers should be used on static (non-changing) objects, so they can be cached browser-side And by intermediate caching proxies Validators are not enough

Editor's Notes
If you’re here, you’re a performance convert. But one of your biggest problems may be trying to explain the urgency of performance to non-techies in your company… and getting higher-ups to commit to long-term investing in performance. Sure, there are lots of high-profile stories of how speeding up pages has been successful for mega-sites…
I talk to a lot of execs, and I hear this a lot. I get why. It’s difficult for mortal companies to see themselves in relation to ecommerce mega-giants thatmake billions of dollars a year and have teams of in-house performance engineers to do their bidding.
Again, performed 50/50 test to see the impact of faster pages on performance:Conversions increased by 9%Cartsize by 11%Sales by 13%
Again, 50/50 test of the site after implementing the Site Optimizer service. Wetracked three metrics among both test groups: revenue per visitor, revenue per visit, and overall revenue. The goal was a baseline increase of 2.5% across all three metrics. The accelerated site dramatically outperformed this goal:Revenue per visit +8%Overall revenue +6%
I talk to a lot of execs, and I hear this a lot. I get why. It’s difficult for mortal companies to see themselves in relation to ecommerce mega-giants thatmake billions of dollars a year and have teams of in-house performance engineers to do their bidding.
The obvious answer is to just implement Site Optimizer, speed things up, then check out conversion rate changes using a segmentation test, but this isn’t an option for everyone. So we developed a hack. It lets you use two tools you’re probably already familiar with – Google Analytics and WebPagetest – to slice your own data a bunch of different ways, and create decent proxies for performance.
Last fall, we performed a study which showed that IE8 is about 25% faster than IE7 across almost 200 websites. Based on this, we felt that browser version is a solid performance proxy for exploring conversion behaviour. Reference original case study: “The first thing we did was perform a Webpagetest in IE7 and IE8. We found that his site was 30% faster in IE8.”
Explore different connection speeds within IE8. First, perform Webpagetests on the different connection speeds, and then compare them to the results in Google Analytics.If you’re using Google Analytics, I think the easiest way to get this data is with a custom report that looks something like this. (reference Google Analytics screen grab)From case study: “Again we found a remarkable relationship between connection speed and order value. On average, online shoppers using T1 connections spent about 11% more than shoppers with DSL connections. And shoppers with T1 connections spent roughly 32% more than those using dialup.”
To pass any hardcore statistical muster, a much more in-depth regression test would need to occur. But these early proof points are enough to convince many non-believers that performance matters and they should invest in it.
In a real-world application of this approach, with all variables accounted for, the optimized site still outperformed the unoptimized site.
From case study:Before I released this hack into the wild, I needed to apply this methodology to one last test to determine if it had any validity in the real world. I took a Strangeloop customer who had been through a rigorous month-long 50/50 test. In this particular case, with all other variables accounted for, the optimized site outperformed the unoptimized site. On average, order value for the optimized site was 20% greater than for the unoptimized site
This is what you need to start with.You may have your own variation on this. What’s the best way of showing this?
With a table?This is a table showing the load time and start render time for the top 20 ecommerce sites of the 2009 holiday shopping season. There’s some interesting data here, but if you were a performance newbie, you wouldn’t know it.Tables show that you’ve done your homework and tabulated your data. Okayin the appendix of a performance report, but they’re not goingto light fires under any butts.
Better…Side by side comparison graphic. (It’s easy to create using Webpagetest’s visual comparison feature. First, run your side-by-side test, then click the “Export filmstrip as an image” text link on the bottom of the results page.)You can see how your site loads, frame by frame, compared to your competitors.Interesting, but requires a bit of scrutiny to understand.Good to include in a competitive analysis section of your performance audit, but not a showstopper.
This is when you share the findings of your 5-minute speed/benefit analysis. It can be as simple as Google Analytics screenshots like this.
After you’ve grabbed attention, then start providing big-picture context.Use concrete benchmarks to create goals… and introduce competitiveness.You can get this data from companies like Gomez, which updates benchmarks every week.This index may focus on larger companies, but these numbers are relevant to all companies. Here’s why…
Users don’t care if your company is large or small. They expect all sites to load fast.
