Cursor feels slow and unreliable for code, how can I improve its performance?

If Cursor feels slow or unreliable, start by updating to the latest stable version and restarting the app to clear stuck background processes.

Large projects can slow indexing, so exclude heavy folders like node_modules, build, or .git from search and AI context to reduce memory usage.

Disable unused extensions and turn off experimental or beta features, since they can increase latency and instability.

If performance is still poor, increase your system’s available RAM, close other heavy apps, and check your internet connection because Cursor’s AI features depend heavily on stable connectivity.

If none of the above solutions work, please feel free to share your experience. You can also file a complaint on our website.
