See below for how to view the gecko profiles from within treeherder.
==== Customizing the profiler ====
If the default profiling options are not enough, and further information is needed the gecko profiler can be customized.
===== Enable profiling of additional threads =====
In some cases it will be helpful to also measure threads which are not part of the default set. Like the '''MediaPlayback''' thread. This can be accomplished by using:
# the '''gecko_profile_threads''' manifest entry, and specifying the thread names as comma separated list
# the '''--gecko-profile-thread''' argument for ''mach''' for each extra thread to profile
==== Add Profiling to Previously Completed Jobs ====
