These settings substantially speed up linux as a client to a shared satellite connection. Two way system: Place the following in /etc/rc.local or /etc/boot.local depending on your linux distribution. echo 224360 >> /proc/sys/net/core/rmem_default echo 224360 >> /proc/sys/net/core/rmem_max echo 64 >> /proc/sys/net/ipv4/ip_default_ttl echo 0 >> /proc/sys/net/ipv4/tcp_timestamps echo 1 >> /proc/sys/net/ipv4/tcp_sack echo 1 >> /proc/sys/net/ipv4/tcp_window_scaling ifconfig eth0 mtu 1460 Note: Try these settings first. If you find that your download speeds are at or over 1,500kbs with these settings, then change 224360 to 474280, so that you can get the full download speed potential available to you. If your speeds are ALWAYS below 1,500kbs, raising your rmem any higher than 224360 won't help, and may actually hurt your connection speed. Some people have also gotten better download speeds with a MTU of 1500 rather than 1460 One way system: Place the following in /etc/rc.local or /etc/boot.local depending on your linux distribution. echo 134900 >> /proc/sys/net/core/rmem_default echo 134900 >> /proc/sys/net/core/rmem_max echo 64 >> /proc/sys/net/ipv4/ip_default_ttl echo 0 >> /proc/sys/net/ipv4/tcp_timestamps echo 1 >> /proc/sys/net/ipv4/tcp_sack echo 1 >> /proc/sys/net/ipv4/tcp_window_scaling ifconfig eth0 mtu 1460 Note: Some people have also gotten better download speeds with a MTU of 1500 rather than 1460 got feedback? by celtictiger edited by seagreen |
