[Mldonkey-users] max_opened_connections

[Simon Eilting]

Hi all,

 today I discovered something really interesting: When I had 
max_opened_connections set to 400, I rarely got one single byte 
downloaded, no matter how popular the file, then I set it to 100, and, 
voila, suddenly, I have download rates between 1-5 k/s. I tried to find 
out why this happens (I expected it to be the other way round), and 
this is my explanation: If there are too many opened connections, my 
provider (German t-online) begins dropping them. It's 512 if I am 
correct. So i did 'echo "512" > /proc/sys/net/ipv4/ip_conntrack_max', 
and then lowered max_opened_connections until no more messages like 
'ip_conntrack: table full, dropping packet.' would appear in the logs. 
It is now set to 130, which seems to be the best setting. Can anyone 
confirm that providers are dropping connections (especially t-online), 
and/or that this is remotely connected to download rates of mldonkey?
