Gecko Profiler
|
|
==============
|
|
|
|
The Firefox Profiler is the collection of tools used to profile Firefox. This is backed
|
|
by the Gecko Profiler, which is the primarily C++ component that instruments Gecko. It
|
|
is configurable, and supports a variety of data sources and recording modes. Primarily,
|
|
it is used as a stastical profiler, where the execution of threads that have been
|
|
registered with the profile is paused, and a sample is taken. Generally, this includes
|
|
a stackwalk with combined native stack frame, JavaScript stack frames, and custom stack
|
|
frame labels.
|
|
|
|
In addition to the sampling, the profiler can collect markers, which are collected
|
|
deterministically (as opposed to statistically, like samples). These include some
|
|
kind of text description, and optionally a payload with more information.
|
|
|
|
This documentation serves to document the Gecko Profiler and Base Profiler components,
|
|
while the profiler.firefox.com interface is documented at `profiler.firefox.com/docs/ <https://profiler.firefox.com/docs/>`_
