Describe the Bug

Cursor Tab autocomplete suggestions started appearing with a noticeable delay (~3 seconds) after I stop typing. Previously they were nearly instant.

Steps to Reproduce

  1. Open any .ts or .py file
  2. Start typing in a function body
  3. Stop typing and wait for a Cursor Tab suggestion
  4. Notice the roughly 3 second delay before the ghost text appears

Expected Behavior

Suggestions should appear within about 500 ms after I stop typing.

Operating System

MacOS

Version Information

Version: 3.7.20
Layout: glass
Build Type: Stable
OS: Darwin arm64 25.4.0

Additional Information

  • The issue started after updating to 3.7
  • It happens in both local and SSH remote workspaces
  • CPU and memory usage look normal during the delay

Hey, thanks for the report. On our side we don’t see any Tab latency anomalies on your account, so it looks like something in your local environment. Let’s narrow it down.

A few things that would help:

  1. Run Cursor Settings > Network > Run Diagnostics and send the result. Since the delay happens both locally and over SSH, it’s worth ruling out anything network-related.
  2. Check whether you’ve hit the Free tier limit for Tab completions (2000/month). When you’re close to the limit, requests can start queuing.
  3. Try launching Cursor with extensions disabled using cursor --disable-extensions from the command line and see if the delay changes. This will show whether something in the extension host is interfering.

Let me know what the diagnostics show.
