High CPU Usage by Cursor Server - Need Help with Resource Limiting

General
1

Hi everyone,

I’m experiencing some significant performance issues with Cursor server on my development machine. While the server itself is quite powerful (for personal use), Cursor is occasionally consuming 100% CPU across all cores, which is causing problems with my other resource-intensive applications.

Current Situation:

  • Running multiple trading bots and other CPU-intensive applications
  • Cursor server sometimes maxes out all CPU cores (all red in htop)
  • This causes lag and performance issues with other critical applications
  • Even when “normal”, Cursor still uses significant CPU resources

Server Path showing high usage:
/root/.cursor-server/cli/servers/Stable-001668006cc714afd397f4ef0d52862f5a095530/server/node_modules/@vscode/ripgrep/bin/rg

Questions:

  1. Is there a way to limit Cursor’s CPU usage or configure resource constraints?
  2. Are there any known issues with ripgrep consuming excessive resources?
  3. Can we configure Cursor to use fewer cores or limit its background processes?

I’ve noticed this is particularly intensive when:

  • Opening new files/projects
  • During background indexing
  • When using code intelligence features

Any suggestions for optimizing Cursor’s resource usage while maintaining functionality would be greatly appreciated. I need to ensure my trading bots maintain consistent performance.

System Details:

  • Linux server
  • Multiple cores (all being utilized by Cursor)
  • Running latest Cursor version

Thanks in advance for any help or guidance!
