Huge Memory Usage on macOS

[mrzzmrzz]

Hey, thank you for your efforts. I've noticed an issue. On the macOS 15.5 (Apple Silicon M1) platform, as an LSP, I've observed that pyrefly is consuming a very large amount of memory, which seems rather unusual. In comparison, for the same project, using ty, I found that the memory usage is significantly lower than that of pyrefly. Is this level of memory usage expected?

This is for pyrefly:

This is for ty:

Hi! Is this an open source project/are you able to share repro instructions? If not, are you able to share information on the list of dependencies for the project?

On the open source project Protenix.

@mrzzmrzz is this when opening in the IDE or running check?

Yes, I use pyrefly as the lsp for Zed editor.

@mrzzmrzz Sorry for the slow turnaround time on this! We're having trouble reproducing the memory consumption you're seeing. It would be super helpful if you could do the following when you have a moment:

• Could you check if you still have this problem with Pyrefly version 0.30.0? We recently fixed Excessive memory usage with many pyrefly processes that still appear after VS Code reloading/stopping #853, which may help.
• If you're still seeing the problem, could you provide repro instructions?

Thank you!
