Startup Activation Takes Too Long

[mh-firouzjah]

Type: Performance Issue

On opening new instances of vscode the startup activation of vscode-python extension takes too long and it is even worse than what it shows, because for example in the time of writing I can see vscode tool Running Extensions shows that it took 8044ms for vscode-python but the actual time varies and it is way more than this, it is about 3min. the extension tries to analyze all python files in the root directory and other applicable places so it will be very time consuming.

Extension version: 2023.18.0
VS Code version: Code 1.83.1 (f1b07bd25dfad64b0167beb15359ae573aecd2cc, 2023-10-10T23:45:31.402Z)

Well thank you for attention, here you are.

[karrtikr]

Can you disable the Pylance extension and see if it makes a difference?

[karrtikr]

Can you disable all extensions except Python and provide the profile again? thanks
