I'm pretty sure gprof works with C++ frontend as well, but like I said I think gprof was a dead end anyway (for the reasons described before), so never mind. > Oprofile needs to be compiled from source for my Os Yeah, oprofile needs some work to run *and* providing useful output. > but did find Sysprof available for quick install.

Looking at your data, did you capture the entire app's life time, that is from app start over instrument loading up to the point where rendering caused the performance issue you reported? Because usually what you do is limiting eithering capture or afterwards analysis to the time period where the actual performance issue happens. In this case we are only interested in the period where playback happens and the audio dropouts occur. We don't want to have the time periods in the analysis data where the instrument was loaded, because that taints the picture. /Christian _______________________________________________ Linuxsampler-devel mailing list Linuxsampler-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxsampler-devel
