I've used both JProfiler and YourKit Profiler. They both are
comparable in price and features. For my specific application
(OpenSuse 10.2 Linux, JDK 6, Tomcat 6), Yourkit worked better since
JProfiler reported a lot of CPU time spent in the Tomcat HTTP request
threads which threw off my CPU prof
If you're open to using JRockit, the BEA/Oracle JVM, I've been pretty
impressed with the profiler that comes with it - Mission Control.
Mission Control works with Sun JVMs too, but to take advantage of some
of the more advanced features, you'll need JRockit.

YourKit is my first choice as well. When it comes to licenses, the
nice thing is that they have an early access program where you can
download devel
Hi MassH
+1 for JProfiler, I've used it through the last several versions/years to
profile anything from Swing apps to Weblogic EJBs and its always had the
goods. It will pinpoint performance and allocation hotspots in your
application with lots of helpful stats. At 499USD it's probably a bit exxy
It's not free, but YourKit (http://www.yourkit.com) is an excellent
profiler.
List price is $499 per copy or five copies for $1199.

I played with Eclipse's TPTP (http://www.eclipse.org/tptp/) a bit more
than a year ago. The UI was nowhere near intuitive and getting the
agent to work on Linux was a real challenge -- there was
documentation, but it was somewhere between wrong to begin with and
outdated. After a few trips to the
jvisualvm.exe looks great as a basic memory/thread/CPU monitor. It's
basically like jconsole.exe. However, the profiling function seems
broken. When I hit the "profile" button, it hangs with the "Connecting

just to see the tool wor

It's been a while since I tried looking for a free profiler and as I recall, I
ended up using a trial version of something. As far as polling memory usage at
runtime, there are indeed some API for this in java.lang.Runtime: freeMemory(),
maxMemory(), and totalMemory(). The docs are pretty good
