This repo aims to prove that something is wrong with APFS on macOS, but is also a good stress test in general when changing machine tooling that wants to oberve fs events (such as security tooling / EDR / virus scanners / etc).

Steps:

1. Setup
2. Gather Results
3. Report / PR with your Results ❤️

git clone https://github.com/NullVoxPopuli/disk-perf-git-and-pnpm.git
cd disk-perf-git-and-pnpm

pnpm install # Fill the cache so we don't hit the network during testing

time ( git clean -Xfd; git clean -fd )

Windows Powershell:

Windows Powershell:

(Measure-Command { pnpm install }).ToString()
