Literally just upgraded before seeing this post; I had 31 outdated packages and the first thing I saw was how blazing fast it was! I looked online to see if something changed and saw this post.
Speed was my biggest complaint about brew, so I'm glad to cross that one off my list of things I don't like about brew.
Thank you for your hard work BTW, brew's been a lifesaver on macOS and immutable distros.
Rewriting a program in Rust (specifically) really only makes sense for a few reasons:
1) the existing implementation is in an unsafe, cumbersome language (C, C++).
2) the existing implementation language is too slow and that slowness cannot be worked around.
3) the implementation is enormous, in a dynamic language and you desperately need stricter types. But this doesn't really favor Rust specifically.
1 doesn't apply because Ruby is garbage collected. It's doubtful 2 applies just given what homebrew does: the long pole is always going to be I/O. The performance improvements in version 7 seem to mostly be due to doing more concurrently. I highly doubt the Ruby-ness gets meaningfully in the way.
I was kinda kidding because parent called it "blazing" fast lol. I didn't think it was Rust. Blazing fast software is reserved as a descriptor for Rust programs :)
i just tested and `mise bootstrap` is over twice as fast at installing when a bottle was in the cache. other commands like `status/check` are 20-30x faster. that's without spending much work at all on perf—i'm sure i could bring these numbers down much further.
