[ajug-members] aspectj

[mike stittleburg]

yep, i've used jprofiler quite a bit when i used to do performance work. It
works pretty well but it's to
heavyweight for load testing. I tried JIP jiprof.sourceforge.net but it
still puts to much of a drag on system. Netbeans has
a profiler too (and it's free) and i might take a look at that.

thanks,
mike

I've used JProfiler quite a bit to profile an app within JBoss, and
had good experiences with it.

The thing that worries me about a roll-your-own profiler via AOP is
that you may end up seeing some of the data (i.e method timing), but
you may not have any visibility into other things that could be
harming your app's performance (i.e memory leaks, unexpected code
paths, etc).  Profiling is really hard to do well, and for my money
using someone else's experience (i.e the JProfiler folks) is well
worth it.


Just my $0.02 --
