I found large amount of inclusion (as measured in bytes) to slow down vcx even more than prg, especially in classes having too many methods for my taste (apporaching god-classes). Each file opening will give a special pause as well.

Since fileopening seems to be even more of a showstopper in your case, you might check how much the virus scan / possible path arbitration (security/network availabiltity) is involved.
