Hi Dave, great, thanks!

I am mostly interested in single-thread performance on different ISAs
and different microarchitectures.

Microbenchmarks are easy, I attached a couple of quick ones I use in
an offline mail.

Single-threaded (preloadindex=false), cached and uncached, git diff on
an unmodified tree is slightly more real world.

And then anything else you can think of.

Thanks,
Nick
