Anysphere Python extension is unusable

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Since cursor forced the use of Anysphere’s Python extension, coding in python is almost impossible. It’s terribly slow, we have to wait about 5 to 10 seconds to save a file since the server is busy.

We use Anysphere Python extension as we previously used Pylance, with strict type checking and import organization.

Please fix this urgently otherwise we’ll be forced to cancel our organization subscription and request a refund.

Steps to Reproduce

Install Anysphere Python extension anysphere.cursorpyright, code in python. Cursor is now terribly slow, sometimes it even freezes or dies.

Expected Behavior

It used to work just fine with Pylance.

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Same issue here… makes the entire IDE unusable when enabled….
I type 4 characters and then the whole thing freezes because it has to analyze 15 files…

Can we at least have an option to only run analysis on save, or only after N seconds of no typing activity??
