pyvsc performance dominated by stack frame operations in inspect module about pyvsc HOT 1 OPEN

Hi @grahamcx,
Indeed, for some reason, call-stack inspection is quite slow in Python! Out of the box, PyVSC should omit the work needed to capture source information about classes (something it currently needs to do every time a class is instanced). PyVSC still captures source information about covergroups, but the hope is that these are created much less frequently so the overhead is significantly lower.
Here's a link to instructions on how source-info capture is enabled: Capturing Source Information. Can you confirm that you are not setting the global environment variable, and that your class decorators don't use 'srcinfo=True'?
If things are still slow after confirming that source-capture should be turned off, it might be worth checking the version of PyVSC that you're using. 'Capture off' has been the default policy for quite some time, but I know it's also easy for older packages to hang around systems as long as they're mostly working.

Please let me know either way if you're able to resolve the issue!

Thanks,
Matthew
