Yeh, we need multiple large benchmarks run on a regular basis.
My understanding is the community has two 8-core servers to run
benchmarks on, but I'd quite like to have some details on where these
are at. One is likely to be running RHEL, one Solaris.
We also need performance regression tests, which is a slightly different
thing even if they do sound similar.
