High CPU on Intel Mac (1000%+) - Python Language Server?

Describe the bug / provide steps to reproduce it

Zed seems to be incredibly resource hungry when dealing with a reasonably sized Python FastAPI app. CPU usage is constantly bursting to well over 1000% as indicated by iStatMenus and Activity Monitor and editor slows to a crawl.

It only occurs when Zed starts and looking at the logs, appears to be when the language server is doing it's thing. Not sure where to start debugging here, but something definitely doesn't seem right unless Zed is trying to help me Sous Vide my thighs with my MBP.

Zed Version and System Specs

Zed: v0.166.1 (Zed)
OS: macOS 15.1.1
Memory: 64 GiB
Architecture: x86_64

If applicable, add screenshots or screencasts of the incorrect state / behavior

If applicable, attach your Zed.log file to this issue.
