Hey there, I'm a victim of having a cable connection with a very bad upstream connection. Downstream is fine, who'd complain about 300 kilobytes per second? I wouldn't. My upstream however, sucks. Uploading a file at 7 kb/s generates a latency of ~ 500 ms. That's just annoying. Ok, so I won't upload much. Done. No problem. Well, sadly, my IPv6 tunnel generates A LOT of overhead. It's quite logical it generates more than a normal ipv4 connection, without a tunnel, but some testing proves having 100 kb/s downstream through my tunnel generates 8-9 (!) kb/s of upstream traffic, rendering my entire connection kinda useless. I think it must be possible to reduce this overhead, by tweaking some TCP settings, however, i dont have any clue on what or where. I've been searching on Google, on this forums and others. Haven't come across a single doc or thread on the subject. Any suggestions? OS: Linux 2.4 (Slackware 9)
