Issue: Since latest update on 8/15 jupyter notebooks in Vs code very slow
Labels: under-discussion,notebook-output


Type: <b>Performance Issue</b>

I have a large machine with plenty of ram.  I have been using notebooks in vs code for a long time.  It seems that lately, cell execution has gotten very slow.   I have disabled extensions and restarted several times and swapped out virtual environments.

VS Code version: Code 1.92.2 (fee1edb8d6d72a0ddff41e5f71a671c23ed924b9, 2024-08-14T17:29:30.058Z)
OS version: Windows_NT x64 10.0.22631
