My favorite bittorrent client has been released for the Mac. I've just finished downloading and was looking through the screens and configurations. I didn't have a chance to test it yet because I had a download in progress on my current client, Transmission. When I get home later I'll be sure and try it out. Transmission has been doing great, but I always felt the speed of transmission was consistently underwhelming. Maybe it was the clients I connected to but when I ran µTorrent Windows in a XP VM it got the job done in half the time. Plus the memory footprint and filesize was minute compared to just about every other client.
I just remembered my previous favorite client was Tomato Torrent. It was nothing more than a window dialogbox showing the progress of the current download. The memory footprint was relatively small, but as you spawned more downloads each one would take up the same amount of memory. This was 2002 and memory was cheap, but even 1GB of RAM cost a little bit of money. So accumulating 8-10 open windows used about 20-40% CPU and 150MB or RAM.
