It was slower than that, incredibly slower.
One time it took me 7 hours to download 48.5mb when I was on dialup, those days were so frustrating.
I have a wireless thingy (dongle), and my speeds are quite fast. Earlier today I downloaded something called Desk Space for Vista which was 5.81mb and it only took 40 seconds to download. I think you need to tweak and adjust your settings, and I think you may also have to remove some unwanted unused programs that requires your PC's resources and draw them away from focusing on your wireless dongle or whatever you have for your wireless internet (if a dongle it would naturally slow down due to it being a USB device for some reason?).
DCEmu is quite often slow, I'm suprised also that you made it to DCEmu with dialup. Cause slow and slow equals stop, dialup will be abolished in a few years (hopefully) :D
