Interesting.. I know windows does a lot of stuff that it really shouldn't be doing...
For example, when I go from one device to another to another, say to check MAC address in cable modem firmware on 10 boxes in a row, Windows web browsers will lock right up for 2-3 minutes. Makes no sense.
Anyway, the thing is, there don't seem to be a lot of recommended speed tweaks for windows networking. Or, there weren't a few years ago when I would have been all over that stuff if it was around. So, your experience is somewhat surprising.--
