Is this on Intel?

Here's what I get on M1 chip (the basic sort on MacBook Pro 13", not even Pro or Max) and macOS 12.3 Beta. Times are much shorter.

I tried several invocations to get output formatted similar to yours, finally realizing time is a shell command (with zsh the default on Monterey, while you seem to be running bash given your "$" prompt), and /usr/bin/time is a separate utility.

texlive.tlpdb is ~ 17 MB.
