There are plenty of IO operations inside Tap object, and it will be more when implementing formula alias reverse look up(e.g. list all of alias names for a formula). So let's cache them. Some benchmark: $ time brew info $(brew ruby -e 'puts Formula.tap_names') > /dev/null Before: 6.40s user 2.42s system 96% cpu 9.134 total After: 4.75s user 0.77s system 97% cpu 5.637 total Closes Homebrew/homebrew#44377.

It looks like you tapped a private repository. To avoid entering your

caching or issue the following command:

cd #{tap.path}

git remote set-url origin git@github.com:#{tap.user}/homebrew-#{tap.repo}.git
