Operating System Notes

One NIC bound per CPU.
Each NIC's TX queue length set to 1000 via ifconfig, default 100.
ulimit -n 10000, sets number of open files, default 1024.
File systems mounted with "noatime,nodiratime", no inode access time updating.
net.ipv4.nonlocal_bind = 1, allows processes to bind to non-local IP adresses.
net.ipv4.tcp_timestamps = 0, turns TCP timestamp support off, default on.
net.ipv4.tcp_max_tw_buckets = 2000000, sets TCP time-wait buckets pool size, default 180000.
net.ipv4.tcp_rmem = 10000000 10000000 10000000, sets min/default/max TCP read buffer, default 4096 87380 174760.
net.ipv4.tcp_wmem = 10000000 10000000 10000000, sets min/pressure/max TCP write buffer, default 4096 16384 131072.
net.ipv4.tcp_mem = 10000000 10000000 10000000, sets min/pressure/max TCP buffer space, default 31744 32256 32768.
net.ipv4.tcp_sack = 0, turn SACK support off, default on.
net.ipv4.tcp_window_scaling = 0, turn TCP window scaling support off, default on.
net.core.hot_list_length = 300000, maximum number of skb-heads to be cached, default 128.
net.core.rmem_max = 10000000, maximum receive socket buffer size, default 131071.

net.core.wmem_default = 10000000, default send socket buffer size, default 65535.
net.core.optmem_max = 10000000, maximum amount of option memory buffers, default 10240.
net.core.netdev_max_backlog = 300000, number of unprocessed input packets before kernel starts dropping them, default 300.

HTTP Software Notes

net.tux.logging = 1, turns on logging of requests, default 0
net.tux.cgiroot = /, cgi root check, default /var/www/tux/cgiroot/
net.tux.max_backlog = 3000, maximum per-listening-socket TCP backlog size, default 2048
