I need help with a quick fix for Cursor’s lag issue. I’m using a Debian based distro.
Check your extensions, also check if any big file is included in Chat, that crashes it too
Yeah those are good suggestions! A few other things you can try:
- Run
cursor --disable-extensions
to check if it’s extension related - Use Process Explorer (Command Palette > “Developer: Open Process Explorer”) to spot resource-heavy processes
- Enable HTTP/1.1 fallback in settings if you’re behind a VPN/proxy
- Check if you have enough disk space free
More details on performance troubleshooting here: Cursor – Common Issues
For Debian specifically, make sure you’re running the latest version and your system is up to date with sudo apt update && sudo apt upgrade
Where can I enable HTTP/1.1 fallback?
It crashes so badly I could barely visit the settings page
I’ve tried these, nothing change still, between I have 782GB free space available.
It’s certainly all about the file “state.vscdb” which handle the entire composer state (history, conversation, parameters and so on). When it take over >100Mo , Cursor freeze and lag
You have to delete this file and restart cursor… BUT you loose your conversations and history.
I do not understand why devs don’t want to part this file for Cursor not having to read it all every time.
In Cursor’s globalStorage folder :
C:\Users"username"\AppData\Roaming\Cursor\User\globalStorage\
Edit : Sorry, i’m on v0.44.11 i don’t know if folder structure and state.vscdb still exists on last version
Thank you so much @anotio , you’re a life saver. Every works smoothly now
You’re welcome
