That is my question, why connecting via Internet2(Geant<-->Abilene) we have that low bandwidth?? Any problem with the routing? We have configured the sysctl like this to solve some problems whith the routing as recommended by some gentoo stuff. # increase Linux autotuning TCP buffer limits net.ipv4.tcp_rmem = 4096 8388608 16777216 net.ipv4.tcp_wmem = 4096 524288 16777216 net.ipv4.tcp_mem = 97280 977920 9830400 # increase Linux TCP buffer limits net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 net.core.rmem_default = 131072 net.core.wmem_default = 131072 # as per http://lwn.net/Articles/92727/ net.ipv4.tcp_default_win_scale = 0 Thanks for all. -- Linux localhost 2.6.8-gentoo-r3 #6 Wed Oct 6 16:31:23 CEST 2004 i686 AMD Duron(tm) processor AuthenticAMD GNU/Linux
