We have two testers running on the same machine, running the perf tests on clang and MSVC builds. Individual tests can be viewed at the perf dashboard, but it's hard to compare them all at once. I wrote an ugly script to show the results of the last builds side-by-side (attached).

Note that it's mixed whether a higher number is better or worse.

(I need to look into why so many tests just report an energy consumption number, e.g. octane and page cyclers.)
