I have some problems?

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Hey everyone

Is anyone else experiencing massive slowdowns today (Nov 7, 2025)?
For me, Cursor has become almost unusable — code completions take 10–30 seconds, and GPT-5 / GPT-5 Codex often hang or timeout completely.
Even switching to Sonnet 4.5 or Haiku 4.5 only helps a little.

I’ve tried:
– Restarting the app
– Switching between different models (GPT-5 Low Fast, Haiku, Sonnet, etc.)
– Clearing cache and local data

Nothing seems to fix it — everything just feels super laggy today.
Is there any official info about degraded performance or a known outage?
Would appreciate a quick update from the team

Thanks!
Flo

Steps to Reproduce

How can I?

Operating System

MacOS

Current Cursor Version (Menu → About Cursor → Copy)

Cursor: 2.0.64
VS CODE: 1.99.3

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey @flo1109, thanks for the detailed report!

I’m not seeing other reports of slowdowns today, so this might be a network or local configuration issue. Could you please help diagnose:

1. Network Diagnostics:

• Go to Cursor Settings > Network > Run Diagnostics
• Share the results

2. Try disabling HTTP/2:

• Open Settings (CMD + ,) > search “HTTP/2”
• Enable “Disable HTTP/2”
• Restart Cursor and test

3. Check for extension conflicts:

• Run cursor --disable-extensions from terminal
• Does performance improve?

4. Share Request IDs:

• After a slow/failed completion, open CMD + Shift + P > “Report AI Action”
• Share a few Request IDs from recent failures

This will help us figure out if it’s network-related, an extension conflict, or something else. Let me know what you find!

cursor is so slow

I can’t work so….

Thanks for sharing the diagnostics!

Since the issue persists, could you please try the remaining diagnostic steps:

1. Disable HTTP/2: Open Settings (CMD + ,) > search “HTTP/2” > Enable “Disable HTTP/2” > restart Cursor and test
2. Test without extensions: Run cursor --disable-extensions from terminal - does performance improve?
3. Share Request IDs: After a slow/timeout completion, open CMD + Shift + P > “Report AI Action” and share a few Request IDs

Let me know what you find!
