Defaults scope set with path slows down build

Running Jekyll 3.8.3

When setting defaults with path I get a 22 second jump in build time. When I set the scope with type I get a 2 second jump in build time.

  - scope:
      path: "_serveradmin"
      # type: serveradmin
      plugindisclaimer: True

Is this expected?

Yes this is expected. A few versions ago glob patterns were added for path and that affected build performance.

It was much worse before but got better with an update.
