Why not run these on the NVIDIA and Intel GPU perf bots too?

[Daniele Castagna, 2015/02/26 22:23:05]

I wanted to make sure it works on one bot before trying on all of them, but
since both you and Simon seem confident enough I'm adding them.

Do you need the --single-process-tests for android?

[Daniele Castagna, 2015/02/26 22:03:28]

Probably not. I'm removing it.

I don't think you want to run this on a builder.

[Daniele Castagna, 2015/02/26 22:03:28]

I'm going to change it to "Mac 10.8 Perf (1)". I thought any bot with
ChromiumPerf as master would be a perf bot but given your comment that's
probabily not the case.

[shatch, 2015/02/26 22:09:23]

Nah it builds and packages it up for any mac perf bots. See
http://build.chromium.org/p/chromium.perf/builders/Mac%20Builder/builds/73223

You probably want both the Mac 10.8 and 10.9 bots, as well as the various
windows GPU bots.

[Daniele Castagna, 2015/02/26 22:23:06]

Done.
