I find that the downloads go a lot quicker if you only do 1 at once as you gotta upload too(ie - if u dl 3 items then you get 3 uploads and 1 download - it seems to be the way it allocates the bandwidth),Also I dont know if its intentional in the prog or not but it also seems that if your share rating on your last download was high then you get a better dl rate with your next one (if that makes sense) Finally Torrent is the best way to get changed mame roms, you can download 1 file that contains all new and changed roms.
