I was almost certain I had a MR forum account, but apparently not. I've frequented MR for about 5 years now. I've done a forum search as well as a Google search, and I seem to have a pretty specific problem that nobody else seems to have...Hopefully someone here can provide some helpful information. I'm using Transmission on my MBP to download Ubuntu to give it a whirl. I use cable internet with a speed of 5 mbps down/1 mbps up through an ISP that is not known to limit torrent traffic. I can start the torrent transfer, and the download gradually climbs its way to over 1MB/s. It will hover between 1.0-1.5 MB/s for about 10 seconds before shooting down to 500 KB/s and it will stay between 500-700 KB/s for the rest of the transfer, no matter how many peers join in. The interesting thing is I can pause the transfer and start it again, and it will do the same thing. Here's what I've tried: using uTorrent instead, disabling UPnP on my router, having Transmission automatically map a port (56003), using a 3rd party firmware on my Linksys WT54GL router, and not limiting my upload speed at all. None of it has worked. I cannot figure out a way to keep the speed consistently up, even close to its full potential. So...any ideas?
