Just upgraded to 2.0 beta, build 17427. I was downloading 5 torrents at the time I decided to upgrade. I know, not the smartest move, but it was telling nonetheless. My download speed with these 5 torrents when using v1.8.5 was 1.75 MB/s, which is a typical DL speed for my connection. After the upgrade to 2.0 beta, my download speeds (while downloading these same torrents and (presumably connected to the same peers) has hovered around 100-200 kb/s. Both DL and UP speeds are set to unlimited. I have "Enable bandwidth management enabled" but turning it off makes no difference in the DL speed. Any thoughts as to why my download speeds would wither away like this with 2.0 beta. I obviously want to take advantage of my nice 1.75 MB/s speed. Thanks! UPDATE: I did a little reading on the forums and turned off the tcp_rate_control and my DL speeds sprang back up.
