Cursor AI slow or freezing on Windows? This fix worked for me

Feedback

:waving_hand: Hi everyone,

I had serious performance issues with Cursor AI on Windows — frequent slowdowns, high disk usage, and dozens of Cursor.exe processes.

After several tests, I found a simple but very effective solution that completely fixed the issue for me.

:triangular_flag: What I was experiencing:

  • Cursor got slower over time or completely froze
  • 25–30 Cursor.exe subprocesses running
  • Internal SSD (C:) was constantly saturated
  • Setting CURSOR_MAX_WORKERS had no effect

:white_check_mark: My solution:

1. Moved Cursor’s cache to an external SSD (F:)

  • Moved the folder:
    C:\Users\<username>\AppData\Roaming\Cursor → F:\Cursor_Cache
  • Created a symbolic link:
mklink /D "C:\Users\<username>\AppData\Roaming\Cursor" "F:\Cursor_Cache"

I had the same exact problem, and moving the cursor cache to another drive that wasn’t my system drive provide performance relief instantly. Runs good as new. Thanks for the tip.

Dalla modifica, Cursor AI non ha più rallentato o bloccato. ■■ fatto di meglio, ■■ spostato anche il progetto su SSD esterno.
