Profiling Java Application using annotation
This blog will provide details of measuring a performance of a code snippet while developing. This is will very handy to developer to quickly measure the performance of a method while unit testing. Benefits: While developing a feature a developer usually missed out performance parameter which is equally and important nonfunctional requirement. Ideally a developer must make it as a practice to test performance of their code along with unit testing and improved it if it is not fall under acceptance criteria. A quick measurement of performance is to check the elapse time of a method. Most of the time we monitor elapse time using System.currentTimeMillis method. But for this we need to add unwanted statements in our code. Moreover along with elapse time sometime we also required some further information like mean, minimum, maximum, standard deviation and transactions per second over a set time span. All above task for testing performance can be easily carried out by using per
