Optimize drupal
This document provides tips on how to optimize a Drupal site for speed. It recommends using more powerful hardware, configuring the web server with Nginx for static files and caching, using a database server like PerconaDB for performance, optimizing PHP with FPM and opcodes, improving Drupal with caching and removing slow modules, optimizing themes to minimize processing, using a faster search like Solr, and optimizing frontend assets with aggregation, compression and CDNs. The overall goal is to leverage caching, databases, servers and other techniques to make a Drupal site faster.
Drupal caching
- Drupal relies heavily on SQL queries which can burden databases. Caching improves performance by reducing database queries.
- There are different levels of caching in Drupal - from internal block/page caching, to HTTP caching using a reverse proxy, CDN, or custom caching with Drupal's cache API.
- For high traffic sites, saving the Drupal cache to memory (e.g. using memcached) rather than the database is recommended. Opcode caching like APC also provides significant performance gains.
- Profiling a site is important to identify bottlenecks and determine the appropriate caching strategy based on factors like site content and hosting environment.

This session covers the use of non-volatile memory (NVDIMM-N) in a byte-addressable mode with a DirectAccess (DAX), a.k.a. zero-copy file system in Windows Server 2016. In this mode, DAX-aware applications can expect ultra-low latency access (orders of magnitude compared to SSD) to the persistent storage medium and gain significant efficiencies. The open-source NVML library makes this transition easier for apps.
Caching
This document discusses different types of caching that can improve performance for PHP applications. It covers opcode caching, which speeds up code execution; data caching using key-value stores like APC, Memcached, and Redis to cache user data; reverse proxy caching with Varnish to cache responses; and browser caching using HTTP headers to cache responses locally. The document provides examples and advantages of each approach. Opcode caches like Zend Optimizer+ and APC compile PHP to bytecode for faster execution. Data caches store user data to reduce database queries. Reverse proxies cache responses for multiple clients. Browser caching improves load times for return visitors.

Set model and page fault.44
The document discusses the working set model and page fault frequency in operating systems. The working set model defines the set of pages used by a process within a time window. It aims to approximate the program's locality to determine the optimal number of frames to allocate. Page fault frequency is a good indicator of thrashing, with higher frequency suggesting more frames should be allocated.
Avoiding Data Hotspots at Scale
There are two key choices when scaling a NoSQL data store:
choosing between a hash or a range based sharding and choosing the right sharding key. Any choice is a trade-off between scalability of read, append, and update workloads.
In this talk I will present the standard scaling techniques,
some non-universal sharding tricks, less obvious reasons for
hotspots, as well as techniques to avoid them.

Top 10 Scalability Mistakes
My Top 10 Scalability Mistakes talk updated for O'Reilly's Open Source Convention in Portland, OR 2008
Apache Con 2008 Top 10 Mistakes
The document provides tips on common scalability mistakes made when designing web applications and strategies to avoid them. It discusses the importance of considering scalability from the beginning, avoiding blocking calls, caching frequently accessed data, optimizing database and file system usage, and using tools like profilers to identify bottlenecks. The key is designing applications that can scale both up and down based on current needs through a proactive, process-oriented approach.
Scaling PHP apps
Matteo Moretti discusses scaling PHP applications. He covers scaling the web server, sessions, database, filesystem, asynchronous tasks, and logging. The key aspects are decoupling services, using caching, moving to external services like Redis, S3, and RabbitMQ, and allowing those services to scale automatically using techniques like auto-scaling. Sharding the database is difficult to implement and should only be done if really needed.
2013 - Dustin whittle - Escalando PHP en la vida real
This document discusses how to scale PHP applications to meet high demand. It begins by noting that large companies like Facebook and Wikipedia use PHP. It then outlines several techniques for scaling PHP, including: using opcode caches to improve performance; storing sessions in a database rather than disk; leveraging in-memory data caches like Memcached and Redis; doing blocking work in background tasks via queues; and utilizing HTTP caching with a reverse proxy cache. The document emphasizes that performance is important for user experience and business results, and that these techniques can help PHP applications handle high traffic loads.
Scaling Web Apps P Falcone
To scale PHP web applications:
1) Focus on fundamentals like testable code, efficient data structures and algorithms, and designing for change.
2) Optimize performance through caching, using databases efficiently, and leveraging PHP features.
3) Employ techniques like asynchronous processing, parallel computing, and service-oriented architectures to spread load across servers.
PHP Performance: Principles and tools
The document discusses various performance issues that can arise when developing PHP applications and provides recommendations on tools and techniques to identify and address performance problems. Some key points covered include optimizing database queries, reducing network latency, avoiding IO contention, improving CPU utilization, and using tools like Zend Server to monitor performance. The document emphasizes using a scientific approach to identify and solve specific performance problems.
Scaling symfony apps
This document discusses scaling Symfony applications. It begins by introducing the speaker and their experience scaling large applications. It then covers scaling different aspects of an application including the web server, sessions, database, and filesystem. For each area, it provides recommendations such as using PHP opcode caching, storing sessions in Redis or Memcached, considering database sharding for very large databases, and using an abstraction layer like FlysystemBundle to store files in cloud storage like Amazon S3. The overall message is that scaling can be achieved through configuration changes and decoupling services rather than code changes.
Lamp Stack Optimization
Mike Creuzer's presentation on LAMP optimization for the October, 2009 meeting of the Suburban Chicago PHP & Web Development Meetup
Drupalcamp Estonia - High Performance Sites
Rami Jarvinen discusses optimizing performance on Drupal sites. He outlines several caching strategies including PHP opcode caching, Drupal internal caching, page caching, and reverse proxy caching using Boost or Varnish. Memcached can be used as a high-performance replacement for Drupal's database caching. Scaling can involve using a master-slave database setup and serving static files from a separate server. Profiling tools can identify SQL bottlenecks and unnecessary queries for optimization. The optimal solution depends on factors like the number of anonymous vs logged-in users and the capabilities of the hosting environment.
Drupalcamp Estonia - High Performance Sites
Rami Jarvinen discusses optimizing performance on Drupal sites. He outlines several caching layers that can be implemented including PHP opcode caching, Drupal internal caching, page caching, and reverse proxy caching using Boost or Varnish. He also discusses scaling Drupal through techniques such as MySQL master-slave configuration, serving static files from Nginx/lighttpd, and adding frontend servers. Profiling with tools like Xdebug can help identify SQL bottlenecks to optimize. The optimal caching and performance strategy depends on each site's specific usage and hosting environment.
