I tested my solution by creating a directory with 20,000 files in a temporary repo. git rm -r took 17.96s, and git rm -rf took .12s. (This is on an SSD.) That's also a nicer and more intuitive solution than mine. > I wonder how fast "git diff-index --cached -r HEAD --", with the > same pathspec used for the problematic "git rm", runs in this same > 50,000 path project. I'll let the original poster answer this one as well, but it was very fast in my test repo. I'm not very familiar with the code path in question, but it definitely looks like we're avoiding the quadratic behavior in this case. -- brian m. carlson / brian with sandals: Houston, Texas, US https://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: https://keybase.io/bk2204
