# Are We Slim Yet (AWSY)
|
|
|
|
The Are We Slim Yet project (commonly known as AWSY) for several years
|
|
tracked memory usage across builds on the (now defunct) website.
|
|
It used the same
|
|
infrastructure as
|
|
[about:memory](about_colon_memory.md) to measure
|
|
memory usage on a predefined snapshot of Alexa top 100 pages known as
|
|
tp5.
|
|
|
|
Since Firefox transitioned to using multiple processes by default, we
|
|
[moved AWSY into the
|
|
TaskCluster](https://bugzilla.mozilla.org/show_bug.cgi?id=1272113)
|
|
infrastructure. This allowed us to run measurements on all branches and
|
|
platforms. The results are posted to
|
|
[perfherder](https://treeherder.mozilla.org/perf.html) where we can
|
|
track regressions automatically.
|
|
|
|
As new processes are added to Firefox we want to make sure their memory
|
|
usage is also tracked by AWSY. To this end we request that memory
|
|
reporting be integrated into any new process before it is enabled on
|
|
Nightly.
