Hi everyone!
I'm sorry, I'm having sluggish performance when profiling with TPTP 4.2, and by "sluggish" I mean that a 2-seconds method takes about 50s when profiled..
I'm monitoring just execution times, and I filtered the monitored classes to the bare minimum.. Any idea of what could be the culprit? :/
My specs:
- Linux (Fedora 6) kernel 2.6.20
- Eclipse 3.2.2
- TPTP 4.2 (from Callisto website via Update Manager)
- Agent controller 4.3.0
I'm trying to profile a local class, which uses Hibernate for persistence.
Many thanks in advance, please ask if you need more information!

Federico,
The new JVMTI Profiler in TPTP 4.4 will probably work faster in your
case. The main reason is that only monitored classes (i.e., classes
which pass the filter criteria) are instrumented and the rest of the
application (including the Hibernate framework) runs at full speed.
To use the new profiler, you'll need Eclipse 3.3. Please check the TPTP
4.4 download page for the exact prerequisites.
HTH,
Asaf

Whoops, that's LD_LIBRARY_PATH of course, sorry ^^;
