Issue Description

I’m finding intellisense incredibly slow in some circumstances (often several tens of seconds). This also affects the time take for the great new code lens stuff to appear. I have quite a large repo, but by trial and error I found that knocking out all the DSC modules makes things blindingly fast. Adding even one DSC module back in makes things noticeably slower. I tried third party DSC modules (xPSDesiredStateConfirugation or xWebAdministration) and the behaviour’s the same.

Attached Logs

The logs below are from two vscode workspaces: one has a third-party MySQL module, and the other has that module plus xPSDesiredStateConfiguration version 6.4.0.0. All I am doing is opening the MySQL module file and waiting for the code lens to appear in front of the first function. You can see from the timing that there’s a 8-second lag before line 1537 of the version with DSC.
