A few things come to mind. How many of the windows are running slow? Do the rear windows run slow as well? They don't get used nearly as often and thus could serve as a comparison. Some will say that the age of the motors is the problem. I can understand that on the driver side window as that gets put up and down a lot. So.
There could be a possibility that you might want to replace a motor or two, but first.
The one thing I have found it that the rubber in the guides gets dry, etc. I would try spraying the track with Son of a Gun or something similar. Make sure it gets to the full length of the track. This will act as a lube and hopefully help condition the track material. It may take a little time and a couple of applications to work but it will help. You could even open a door panel and put some spray grease on the moving parts as they may be very dry. Last resort of course is new parts.
