getActiveInterpreter can take a long time.

We should cache this value.
Or ask the python team why this isn't cached.

If we cache, we should update when they get their new value.

Not sure if we have a clear customer validation here, but I see the code changes for this. Validating.

[rchiodo]

Sorry should have added validation steps.

The delay was apparent when opening new notebooks. The kernel picker would take 5 seconds to even appear. All of this time was spent searching for the active interpreter on my own machine.

Yeah, I do see it being a bit snappier than before. I don't have exact numbers, but seems to be an improvement.
