v4 v5 5 5 OProfile does a system-wide profile using performance counters. It can also generate annotated source/assembly just like VTune. Unfortunately, because GHC can't export source-level debugging symbols, OProfile cannot do source-level annotation of GHC programs. 6 6 7 It can be installed from a package on Ubuntu, which is cool. But beware: Ubuntu bug 172495: [[https://bugs.launchpad.net/ubuntu/+source/oprofile/+bug/172495/]] : change the `/bin/sh` to `/bin/bash` at the top of `/usr/bin/opcontrol`. 7 It can be installed from a package on Ubuntu, which is cool. 8 8 9 9 There seems to be a problem with the counters just stopping arbitrarily, requiring a restart of the daemon.
