| From: Gaurav Kushwaha [mailto:[EMAIL PROTECTED] | Sent: Monday, 29 January, 2007 06:11 | | I have an application that has been working fine for last half an year | or so. Recently the load has started increasing and the time it takes to | serve a request is going up significantly. When I look at the resource | utilization(memory and CPU), it hardly shows an increase. Garbage | collection | is also not the culprit. What might be causing this performance hit ?
The first step is to measure the different components of your app to see where the degradation is. Is it an external resource (database, message server, etc.)? Is it internal? Where is the app spending all its time? If you can, get a performance analysis tool like JProbe. Otherwise, maybe you could instrument your code with simple timestamping of method entry/exit points. The first step to solving performance problems is always finding out where the performance is going... ----------------------------------------- ------------------------------------------------------------ The information contained in this message is confidential proprietary property of Nelnet, Inc. and its affiliated companies (Nelnet) and is intended for the recipient only.
