It's yjit

Rails.application.config.yjit = true

It's a combination of Apple Silicon + x64 Ruby

tagliala commented 3 hours ago

After several tests, I came to the conclusion that it is a combination of Apple Silicon (?) + x64 Ruby + YJIT

With ARM Ruby + YJIT the difference is negligible, but x64 Ruby + YJIT is slower by several orders of magnitude

This does not seem to affect CI

Apparently this also affects Intel Macs, there could be an issue with macOS + Ruby x64 + YJIT

I've tried to upgrade rust, but there is no difference

In the end, to fix this issue on my machine, I've reinstalled Ruby x64 without YJIT

rvm reinstall ruby-3.3.6 --with-opt-dir="$(brew --prefix openssl)" --with-libyaml --disable-yjit
