Editor's Notes
- http://www.webperformancetoday.com/2013/05/06/psychology-waiting-faster-online-checkout/ Does anyone like slow applications. 5 seconds is actually a long time.
- So more mobile devices over higher latency radio networks and larger webpages. Hmm sounds like a recipe for application performance problems. http://www.fiercewireless.com/special-reports/3g4g-wireless-network-latency-how-do-verizon-att-sprint-and-t-mobile-compar http://techcrunch.com/2013/05/29/mary-meeker-2013-internet-trends/ http://www.pewinternet.org/fact-sheets/mobile-technology-fact-sheet/
- So here we have the scenario – users want applications always on always fast and available everywhere – every location and on every device. Applications are often not written to deal with latency – they are chatty, and not optimized. The network usually works pretty well actually but you can’t alter the laws of physics For mobile users there is going to be a carrier network involved – local network admins are not going to have a lot of control over this. So what can you do Can you lower the users expectations – no, can you reduce the latency in the AT&T carrier network – no. Well the network works ok, can you recode the app? Probably not easily. So what can you do?
- You can use a CDN – and that might be a good idea – but they come with variable costs and are really just fancy caches local to your users – that might not be enough You can deploy additional infrastructure maybe some dedicated acceleration devices but they again cost money and can be complex – plus another o/s devicece learn Or you can enable acceleration as part of a new or existing F5 deployment.
- The idea here is simplicity. Turn on three things and make it go a bit faster.
- TCP – now with new features like rate pacing and advanced congestion control algorithms which have been tuned to deal better with latency rather than loss. This genuinely will make a difference.
- HTTP protocol inefficiencies exacerbated on mobile devices Additional latency inherent in WAN No multiplexing of requests in a connections – needs more connections
- SPDY Multiplexed bi-directional streams within TCP connection Fewer network connections required HTTP header compression NB we don’t support SPDY push yet – so be wary of number that give performance improvements of SPDY when comparing a SPDY enabled server vs our SPDY profile.
- Here we are talking about Compression IBR Intelligent Client Cache Content spooling These are components of the fundamental policy that we are advising be deployed.
- All this can be delivered from the all-active, highly available, elastic, multi-tenant application services fabric.
- So we have given you a simple solution – one that can deliver real results in a few hours of implementation. Have we dumbed down the product? No, all the high end features are still there. Whatever the size of your application delivery problem we have a solution to accelerate it. We will continue to innovate and simplify your life.
- So, you’re convinced – great – how about we give you some idea of the benefits you might see before you start? Use the FAST tool to quickly get a real world assessment of how much we can speed up your site or application. Where we found optimizations, they averaged 30%.
