I have also had trouble with the scalability of TPTP when profiling an RCP app. I also ultimately chose to use YourKit, which does not appear to suffer from the same scalability problems.

I did change my filter in TPTP to only do execution time analysis on com.mycompany.*, but apparently that is still too much data, because when I start to profile, and the Profile perspective shows it has recorded about 1gig of data, it comes to a grinding halt and I have to kill Eclipse and the app that was launched.

When I use YourKit, I launch it standalone (not within Eclipse), and simultaneously launch my app with the -agent parameter, then connect the two together.

@Aurelien: I also learned this feature from Eugene. Very cool and speeds up quite a bit the profiling process.

Ok, I never used the filter as I never explore really TPTP as it was so slow. Thanks for the advice

@Aurelien Profiling my RCP app also took longer. But you can use the filter to profile only the classes you are interested in.

Each time when I tried TPTP I chose another tool for profiling But from time to time I try it again and have the same results Now I use YourKit profiler.

Hi,

Don’t you have any isssues with performance running TPTP? (yes TPTP is here to track down this ^^)
When I tried to use TPTP with my RCP appliction, only launching my RCP app tooks 30min… Is there some configuration that I may be miss? or is it “normal”?
