    Hi,

    Using Azureus Vuze, please see the attached Conntrack settings, Once download starts, , the speeds go upto a\s much as 50-60 KB/s generally, but very soon, come to to 50-60 to 300 b/s. If I go into Conntrack settings and click on drop Idle Connections, almst as soon as i do that, there is a pick up in download speed, but then it dies out again, untill I click Drop Idle Again.

    Please see the attached Netlimiter graph, which shows the traffic for Azureus only, towards the middle of the screen, the traffic almost comes down to zero, untill i pressed Drop Idle andit picked up again. Is anything wrong wiht my Conntrack settings this is causing this?.

    Thanks for any help.

    I'm in the UK, on DSL, have bound a fixed port in Azureus and forwarded it to the internal IP of the machine running Azureus. I don't think Demon.net, my ISP is throttling Torrents as when I click on drop idle connections, download speeds do go up quite a bit for a while.

    Maybe I should look at running a cron job to schedule drop of idle connections every 5 minutes or something like that??

    What is the number of tracked connections that you see when the speed drops?
    If they are near the limit, check in what state are most of them. If they are in Time Wait, maybe you should change the timeout to lower value.
    If you see a lot of established connection, you can try to limit the number of connections in your torrent client.

    I bet it's not a popularly seeded file, then. Go try d/l a popular linux distro. if its fast then it's the particular torrent's fault.

    Also, if you can't stand the wait, try private trackers/ratio sites. People are GREEDY, haven't you noticed? You've heard of leeching clients, bittyrant, ratio cheating client (bitcomet), etc...

    There's been some past threads on this topic in this forum. Try a forum search ... usually doesn't involve Tomato settings, but your torrent settings. It also might be tcpip related with regard to the number of half-open connections allowed in Windows - one way to tell is to look for event 4226 in the Windows event log.

    There are solutions to both. :)
