JupyterLab is slow/laggy. Reason detectable via logging?

JupyterLab
1

Hi! My JupyterLab is reacting slow. I recently changed from Python 3.9 to 3.10, and it was fast before. I guess that some extension is to blame. Is there a method to change the juypterlab log (see image) to a higher precision to identify the down-slowing process?
