Re: [hibernate-dev] taking timings
Thanks for the tip with japex and byteman (know I know what you can do
with it - always wondered)
In my case perf4j seems still to be the better fit. I am not trying to do
a one time profiling, but
rather implement a built-in component which can be queried for example via
JMX. Very much like the Statistics
bean/class in Core.
Given that I am not happy with everything in perf4j, I'll probably go with
Emmanuel's recommendation
and implement my own stuff maybe with some inspiration from perf4j :)

If you just need timings for some methods, you can write a few Byteman
rules to measure the time spent in those individual methods:
http://www.jboss.org/byteman
It attaches to the JVM as a Java Agent (like the profiling tools).
