Hi,

I'm trying to use a CPU and memory profiler for java development. I found several choices from
http://www.manageability.org/blog/stuff/open-source-profilers-for-java/view

I just want to know which one is most people using in development. Any suggestion..please

thanks.

I tried some of the open source projects, but in the end I used a trial of Jprofiler as it does everything you need out of the box.

Hi there ... you can use the eclipse profiler ... it's pretty good actually and it's free ... check it out:

What you really want is a profiler that you can use in production. In development, use a profiler whose output and GUI you understand best.

Fixing bugs that creep out in a production system is much harder, as they are usually impossible to reproduce in a development environment. But most profiles slow down application to a crawl. In my experience with memory profiling, one known commercial product slows down applications by 10-15 times. SUN's hprof has a slowdown of about 2-3 times, even with disabled tracing.

The only thing that I have found that doesn't screw up application is YourKit profiler. Has great performance, good data capture, but a rather poor heap walker.

We use Quest PerformaSure in both production and QA environments and it works great !

For profiling in development I prefer JProbe. Most stable and powerful tool I used so far.

In my last project I also used Introscope which lets you do some simple profiling in a production environment without much performance impact. This can be very useful.
