For "git checkout" with cold cache, the *bulk* of the time is actually the ".gitignore" file lookups, so if you see a three-second improvement out of 17s, it may not look spectacular, but considering that probably 10s of those 17s were something *else* going on, I suspect that if you really did just a plain "git checkout", you actually *do* have a spectacular improvement of roughly 7s -> 4s! Try with time git read-tree -m -u HEAD HEAD > /dev/null instead. But if that is what you already did, then yeah, the performance improvement for cold-cache wasn't as big as I was hoping for.
