A look at the PyPy 2.0 release
Phoromatic tracker allows you to track only one variable (kernel version), while leaving everything else frozen. They even have support for btrfs snapshots to quickly revert system to a known state.
But seriously, Phoronix tracker is quite useful now.
KS2010: Performance regressions

But the arbitrary mix of operations-per-seconds and seconds-to-complete is very annoying, it means I have to read the fine print on every graph to parse it. Gah!

Single-threaded benchmarks are not pointless. I had regressions in single-thread workloads caused by 'too clever' locking which had higher overhead than good old lock_kernel.
Anyway, it's certainly possible to disable uninteresting benchmarks in Phoromatic.
