Sysprof is a sampling profiler that uses a kernel module to generate stacktraces which are then interpreted by the userspace program "sysprof". See the Sysprof homepage: http://sysprof.com/ for more information Questions, patches and bug reports should be sent to the sysprof mailing list: sysprof-list@gnome.org The list is archived here: https://mail.gnome.org/archives/sysprof-list/ Debugging symbols - The programs and libraries you want to profile should be compiled with -fno-omit-frame-pointers and have debugging symbols available, or you won't get much usable information.
