Hey! I was trying to milk the most out of my 100/100. What I ended up with was something, to me, quite odd. When I hadn't done anything I could ftp things from my server box at 50mb/s and run rtorrent at about 9-10 mb/s at most. After my "tuning" I can only ftp at a very "choppy" 30-40mb/s, but rtorrent runs at about 11mb/s. This is what I did: kern.ipc.maxsockbuf=16777216 net.inet.tcp.sendbuf_max=16777216 net.inet.tcp.recvbuf_max=16777216 according to http://dsd.lbl.gov/TCP-tuning/FreeBSD.html every other setting there was default I believe. I also set these: net.inet.tcp.recvspace: 262144 net.inet.tcp.sendspace: 262144 dmesg: http://pastebin.org/24780 Am I just imagining that rtorrent runs faster? Can't ftp handle high buffers or did I mess something up? Is there something else I could do to make it faster? Setting up polling perhaps? Cheers, Daniel Andersson
