they're running a mac probably it takes forever to rm -rf a directory on macs vs linux.

Have not had this experience. I find Macs to be faster in fact as the SSDs are normally much faster than most linux machines.

This isn't about SSD speed. Reading large file is comparable, but there is a very large overhead on the initial file access because of sandboxing.

Opening (or deleting) an empty file is about 2.5x slower on OSX than on a Linux running in VirtualBox on that same Mac: https://discuss.rubyonrails.org/t/why-is-rails-boot-so-slow-...

You called it. I didn't know OSX was bad for that though

Me either...

Was using a hackintosh and rmbp until about 2 years ago, stopped using mac at work, and in october switched to a new desktop and jumped to linux. Been back in windows + wsl2 for a couple months now.

Back using mac, and most of my windows until a couple months ago, was still mostly linux via VM.

Guess I never realized how slow macos's file system was for deleting files.

edit: Also, for those curious, WSL2 files in Windows is slow, and windows files in wsl are slow... each are fast in their own sandbox.
