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. |
