I have loved the Visual Studio Navigation tool ( Ctrl + , ) since it was first introduced - instead of navigating through my folder structure, I could just find the file or class I need by name. The key has always been that the search was instantaneous - it showed all the relevant results as fast as I could type.
Now something has changed, and almost always there is a big lag before any results appear - I measured it up to 10 seconds. This is approximately 5 seconds in a search that has only one result and should have appeared instantly:

This progress bar also jumps around in a weird way.
Any ideas that might change, or what can I do to get my quick old navigation tool back?
