I try upload limit on 60KB, It's still slow about 300-800KB. When I back to 1.8.5, It's work fine 1MB at least. Have cache peer on both test and I think even if no cache, It's still slow. I'm not try bt.tcp_rate and net.calc yet. Look like 2.0 upload speed better 1.8.5 on unlimited upload.(80-100KB/60-80KB) ... Tesing 6 times with 71MB torrent, on unlimited upload and download. bt.connect = 5, bt.transp = 15 and all settings are same. 1.8.5(17414) - 01.41 m on longest. 2.0(RC3) - 02.59 m on longest. 1.8.5 load speed with cache peer(27%) 1-1.1MB to 30% then drop down speed to 800-900KB. 2.0 load speed with cache peer(27%) 200-600KB to 30% then drop down speed to 500-600KB.
