correctly
sysctl -w net.ipv4.tcp_wmem=’8192 87380 16777216′
sysctl -w net.ipv4.tcp_rmem=’8192 87380 16777216′

default parameters are good, the maximum bandwidth available
the problem Reno and cubic (terrible web page download)
htcp the perfect solution for a single set

sysctl -w net.ipv4.tcp_congestion_control=htcp
or sysconfog.conf paste net.ipv4.tcp_congestion_control=htcp

hi, is there a way to clean these network buffer?
because when I running a LOTs connections.

After two~three hours, I always get
no buffer space available in /var/log/messages.

I wish there is a way to clean the network buffer in opensuse 11.1.

Thanks in Advance!
