That's all pgbench-tools itself uses.
The problem with a performance farm is that it's relatively hard to
donate a performance farm member. It more or less requires expensive
hardware, and a large amount of rigor in testing and normalizing
various aspects of the environment that might otherwise add noise.
Then again, it might only take 2 or 3 servers to make a huge
difference. There are a number of different things that would be
immediately compelling to target with that kind of thing, so the first
step is non-obvious too.
