Running a large consumer web application for a mass audience is challenging task. The more users you have using your application, the more likely problems in application will arise. List two ways to Identify performance problems in web application.

Answer 1

There are several ways to identify performance problems in web application-

1) Poorly Written Code - Web application gets affected by inefficient code, memory leaks, synchronization issues. Poorly written code can lead to plethora of web appilcation issues like inefficient algorithms, memory deadlocks.etc. Older versions of software, or legacy systems can also lead to downfall of performance. Developers should employ best coding practices and also use all the resources available at their disposal like automated tools to develop code for the application.

2) Unoptimized Databases - Database is the core of perfromance. Locking and contention, missing indexes and inefficient queries are some of the common performance issues faced when using a database. Optimized database allows for highest level of security and performance. Developers are encouraged to used scripts and file statistics to check inefficient queries.

3) Load Distribution - Lack of load balancing or improper distribution of load can cause serious problems in the web aplication. Poor load balancing can cause slow response times by incorrectly assigning new site visitors to bogged-down servers instead of others with cycles to spare. If a server receives too many requests then it will be ruined out. So it is advisable to use load testing tools like AppPerfect load test for load testing of your application and server.
