I think it's a seriously *bad* idea to expect existing buildfarm members
to produce useful performance data.  Very few of them are running on
dedicated machines, and some are deliberately configured with
performance-trashing options.  (I think just about all of 'em use
--enable-cassert, but there are some with worse things...)

We can probably share a great deal of the existing buildfarm code and
infrastructure, but the actual members of the p-farm will need to be a
separate collection of machines running different builds.

There's no such thing as a useful performance test that runs quickly
enough to be sane to incorporate in our standard regression tests.
