Netbeans has a profiler built in, though I don't know how well it works and I
don't know if it's been updated for 292. The Sun Studio Analyzer does a very
good job capturing profiles without a lot of overhead though it only runs on
Solaris and Linux. The very latest version supports 292 but I
That seems to be a bug. hprof needs to be updated for 292. I filed 7101843
for this.

DTrace probes are horrendously slow. It even states it in the docs.

Anyway you first need to know what you want to measure and to do this

Charlie,
there are the DTRACE probes in Java on MacOSX (and Solaris) - you might
want to look into those.

FWIW, option 2 (hprof) seems like a no-show on u2b08:

I'm looking to get back into JRuby + Indy work now that the heaviest
conferences are behind me. Part of this involves running larger
benchmarks where the hot spots may not be apparent at a glance. In
order to investigate performance on such benchmarks, I will want to do
some profiling. But what sho
