Just stop working (very slow consuming a lot of memory)

Support Bug Reports
2

Hey, thanks for the report. I see high memory usage and slow agents on version 2.1.49 (macOS) after the update.

Please try:

  1. Disable HTTP/2:
    Settings Cmd+, → search “HTTP/2” → enable “Disable HTTP/2” → restart Cursor

  2. Clear globalStorage (if it’s bloated):

  • Close Cursor
  • Rename files:
    ~/Library/Application Support/Cursor/User/globalStorage/state.vscdb
    ~/Library/Application Support/Cursor/User/globalStorage/state.vscdb.backup
  • Launch Cursor again
    Fix: Slow File Edit, up to 10min wait
  1. Check extensions:
    In terminal: cursor --disable-extensions
    If it’s fine after that, re-enable them one by one to find the culprit
    Fix: SLOW or NO response from the agent

If it doesn’t help, please share:

  • 2-3 Request IDs of slow chats (chat menu → Copy Request ID)
  • Screenshot of Settings → Network → Run Diagnostics
  • Screenshot of Cmd+Shift+P → Developer: Open Process Explorer (which process eats memory)
  • Result of the test with cursor --disable-extensions

Let me know if this helped. If not, I’ll pass it to the team.
