This firmware is an attempt to crack the download limit of just 2 torrents at the same time by using the dstlimit modul from iptables to limit incomming connections. I cannot say if the original Linksys firmware v1.01.06 is by default limiting filesharing. I have also done some speed improvement and kernel patches. There was an big bug in the network-subsystem, too. Please take a look at the changelog for more. I have tested it with tons of torrents, and it works like a charm. The performance is awesome.
