因为你的上载量才3G,所以同时可以在线的种子数量是有限制的。

Total uploaded amount is < 5 GB and your ratio is:
< 0.75 = 3 torrents
< 1.00 = 4 torrents

1.00 = 5 torrents

Total uploaded amount is < 10 GB and your ratio is:
< 0.35 = 3 torrents
< 0.75 = 4 torrents
< 1.00 = 5 torrents

1.00 = 6 torrents

Total uploaded amount is < 25 GB and your ratio is:
< 0.35 = 3 torrents
< 0.75 = 5 torrents
< 1.00 = 6 torrents

1.00 = 10 torrents

照你现在的情况看,现在可以同时在线(包含你已下载完的,只要是它启动了)的种子数是4.
