This just shows off the improvements done by the last few
patches, and gives us a baseline for noticing regressions in
the future. Here are the results with linux.git as the perf
"large repo":
Test origin HEAD
-------------------------------------------------------------------
0003.1: log --raw 43.41(40.36+2.69) 33.86(30.96+2.41) -22.0%
0003.2: log -S 313.61(309.74+3.78) 298.75(295.58+3.00) -4.7%
(for a large repo, the "log -S" improvements are greater if
you bump the delta base cache limit, but I think it makes
sense to test the "stock" behavior, since that is what most
people will see).
