That's excellent! Those all look like pretty nice small code changes that all add up. I especially like the very small "avoid copy" change (https://go-review.googlesource.com/c/go/+/355789 https://go-review.googlesource.com/c/go/+/355789) that adds up to a 30% speedup on many benchmarks. I hope they get included in Go 1.19. Good work!
