Well u may be getting too many processes running and LW isn't exactly at the top of ur computer's priority list. Since u have a fast connection, that doesn't mean anything, everyone has lagg. Try dling from somewhere else, is it just as slow? Try openning LW, click on the Tools tab, Options, and go to downloads, make sure 100% of ur bandwidth is set on downloads, if its not at 100% it will only go about 6KBS. and if its on 100% it should say unlimited.
