+{{warning|We're currently working on some major improvements to Talos profiling in bug 1121571. You'll want to use the in-progress patches from there (or just clone http://hg.mozilla.org/users/mstange_themasta.com/talos-sps-profiling at revision 1a737105cc43), otherwise the results won't be very useful. This work will hopefully land within the next few days. }}
 When profiling is enabled, we use the [https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Profiling_with_the_Built-in_Profiler Gecko Profiler] to capture profiles that can then be displayed by Cleopatra. When running in profiling mode, captured profiles are copied to the upload directory.

+. Apply this patch to your Gecko repository in order to use the good stuff from [https://bugzilla.mozilla.org/show_bug.cgi?id=1121571 bug 1121571] before it lands (which should happen on Jan 22 2015 at the latest):

 You need to set an upload directory and use the --spsProfile command line parameter with Talos to capture profiles and have them copied into the upload folder.
