After trying to optimize my new higher-performance internet link, I have found a few tips to tune up IP traffic.
It is more kernel tweaks, like: /etc/syscntl.d/60--ipv4-tweak.conf contains # http://blog.eukhost.com/webhosting/how-to-optimize-tcp-ip-stack-in-linux/ # # Default settings are: # root@nomad2:/etc/sysctl.d# sysctl net.core.rmem_max # net.core.rmem_max = 131071 # root@nomad2:/etc/sysctl.d# sysctl net.core.wmem_max # net.core.wmem_max = 131071 # root:/etc/sysctl.d# sysctl net.ipv4.tcp_rmem # net.ipv4.tcp_rmem = 4096 87380 4046048 # root:/etc/sysctl.d# sysctl net.ipv4.tcp_wmem # net.ipv4.tcp_wmem = 4096 16384 4046048 # # # # Increase TCP max buffer size setable using setsockopt () net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 # Increase Linux autotuning TCP buffer limits # Min, default, and max number of bytes to use # Set max to at least 4MB, or higher if you use very high BDP paths net.ipv4.tcp_rmem = 4096 87380 16777216 net.ipv4.tcp_wmem = 4096 65536 16777216 Ok, I've done this, and it seems to be about 5% faster. Anyone have some additional suggestions? ><> ... Jack Whatever you do, work at it with all your heart...
