Cursor is taking way too much cpu

Describe the Bug

even when it just seats idle and all i do is hover on cursor , my cpu spikes (have got a minimal py codebase , and i even indexed and excluded libraries from it , to save time on indexing ) yet a 128 ram , is clocked to max when i run cursor.
noticing it today after my update , don’t know if i should return to old version.

Running on ubuntu 24 desktop . normally i never go beyond 8% on my cpu , have i have 40 gb gpu and and i9 core . but since today am getting max cpu at 100%

Steps to Reproduce

just run the latest cursor on ubuntu 24 and try indexing and give a small task like understand my codebase from the ai chat . i get to 100 cpu usage immediately .

Expected Behavior

its meant to be as it was before , minimal cpu usage , because with this i can’t run my other things , vms , llms etc

Operating System

Linux

Does this stop you from using Cursor

Yes - Cursor is unusable

Brother if you have an i9 and cpu is on 100% your cpu may have crapped-out. Have you done a diagnosis on the health of your cpu? What processes are running when you notice this behavior? Can you post a screenshot of a task manager (linux equivalent)?


my cpu can’t have crapped out , when i can stop cursor, return to 2% use on cpu , run 3 llm , 3 vmware , and still do all my other stuffs , and never crossing 16% cpu , but run cursor and i go to 100%

and like i said earlier, before update i can run cursor , and never go above 4% if only cursor , and max 30 , when running all my processes with cursor . today since i noticed , i ran each 1 by 1 to see which is causing it, and nailed it down to cursor, as you see in that image, only cursor currently running , and my browser nothing else!
RG = still belonging to cursor


and now cursor shut down. now just browser and few terminals running

I believe I may have found a fix “rg process taking up all my CPU · Issue #98594 · microsoft/vscode · GitHub” for “rg” related Cursor issues. As you know Cursor is based on VSCode and this seems to be an issue specifically with “”" “search.followSymlinks”: true “”" so set this bool to “false” and see if that solves your issue.

Try like this:

“search.followSymlinks”: false

Can you report back if this works to help others that might have the same issue?

Hi , thanks for taking the time to find that , to confirm “search.followSymlinks”: false , the settings under vscode ?

i think it might just have fixed it , cursor is running and cpu is 2-4% max . now this is what i call a helpful community . 5 star

why would such a single symfollow take that much resources though , and why only after i updated to latest ?

Glad that worked! I have no idea what that setting does haha I just googled it and found that from 2020, since the behavior wasn’t something I’ve experienced and I have the same CPU. Happy coding!

Thanks again , any idea why sometimes cursor freezes , even though everything is running smoothly on cpu , but it just hangs for few seconds then with quit or wait dialog box popping out?
