Hey, thanks for the report. Let’s quickly check common causes of slow agent performance.

Try:

  • Settings > Network > Run Diagnostics and share the results.
  • App Settings (Cmd+,) > “Disable HTTP/2” > enable it, then restart Cursor.
  • If using VPN/proxy/Zscaler - try disabling it or switching networks.
  • Run Cursor without extensions: quit, then cursor --disable-extensions. Did it improve?
  • In Chat, select a specific model (not auto) - did the streaming speed change?

Could you please share:

  • 2-3 Request IDs from slow chats (Chat menu ••• > Copy Request ID).
  • A screenshot of console errors (Help > Toggle Developer Tools > Console).

I’ll pass this to the team.
