Chrome has a performance lab with dozens of device and OS configurations. Pinpoint is the service that lets you run performance tests in the lab. With Pinpoint, you can run try jobs, which let you put in a Gerrit patch, and it will run tip-of-tree with and without the patch applied.
Visit Pinpoint and click the perf try button in the bottom right corner of the screen.
You should see the following dialog popup:
|Bug ID||(optional) A bug ID. Pinpoint will post updates on the bug.|
