Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

After last update the agent terminal became extremely f**king slow! It is insane! ANY command it runs, even simple “cd …/ && whatever_simple_command”, seems like either extremely slow, or even hanging!

I have lost the whole day because I have been forced to run tests manually, instad doing it using a cursor.

You already make money on us, please, MAKE THE PRODUCT F*CKING GOOD! angry emoji

Proper commands’ execution speed like in the system it runs.

I have made two things: reinstalled zsh and seems it works now… hmmm :face_with_diagonal_mouth:

Its definitely the problem with latest cursor update 1.6.42 and not with zsh’s.

I have the same behavior. Terminal commands are extremely slow to start. Simple ls takes minutes to run.

I have cleaned my zsh configuration completely, and over time it became work.
