Cursor pins the CPU anytime I edit any file

Hey, thanks for the report. This looks like an indexing issue with a large monorepo.

From your screenshot, Cursor Helper (Plugin) is using 1284% CPU. That’s the extension host that indexes the project for AI. In large TypeScript monorepos, this is a common problem.

Try this:

  1. Add a .cursorignore file to the project root:
**/node_modules
**/.git
**/dist
**/build
**/.next
**/.cache
**/coverage
**/__pycache__
**/*.pyc
  1. Check project size:
  • How many files are in the monorepo? If it’s thousands, indexing can take minutes.
  • CMD + Shift + P > Developer: Open Process Explorer. This shows which process is using CPU.
  1. If it still doesn’t help:
  • Cursor Settings > Indexing & Docs. Try turning it off.
  • Cursor Settings > Privacy Mode (if available). This might reduce load.

Can you share:

  • Total file count in the project
  • A screenshot from Process Explorer
  • Which folders are the largest in the monorepo

This is a known issue with big projects. The team is working on optimizations, but the .cursorignore workaround helps most users for now.
