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
