Flawless web application performance is the aim of a developmental team and requirement of the business client. Without superlative performance, web applications fail the standards of the web users of today. The internet user is hurried and impatient and if the web application is making him wait to get to what he/she needs, then in all probability you are loosing a valuable customer.
Web applications are often required to start accommodating very large number of users in a very short time window after deployment.
Whenever an application development is agreed upon, a SLA (service Level Agreement) is agreed upon. But in the complex web application scenario, it is virtually impossible to attain impeccable up-times due to several factors that cloud the application performance. The disruptive network factors can range from load-balancing, caching, SOA, third party infrastructure limitations etc.
Often the web applications rely on third party infrastructure support like those of the hosting service providers, internet traffic routers etc. which add further complexity to the performance measurement and issue resolution
Another point to note here is that the performance measuring parameters vary on user basis. If user 1 considers a response time of 3 seconds as satisfactory, another user 2 can feel it is poor application performance.
Thus the only way of measuring web application performance is by following real user transactions and identifying the bugs and bottlenecks as and when they occur.
