Insanely fast. Sadly the leechers I gladly share my stash with always complain about the slowness of downloads on their computer and I go "What? I just tested. Didn't take me longer than it would to earn money to buy this hot sexy stuff; that and my computer did most of the work, not me."
Oddly enough I haven't been inspired to share in a while because of the generally ungrateful attitude to gleeful sharing sprees.
Depending of the place I am connected on, less badwidth you'll need more people you'll deserve. I always use public access structures but at work we have a good connexion speed... for too many people :-P.
Mine's around 80 Mbps in download. Almost 40 in upload. Supposedly, the max I'm supposed to have in download is at least over 100 Mbps...could be my wireless adapter though. How anyone can afford over 200 or 300 Mbps is beyond me!
