Operating System Notes

ulimit -n 10000, sets number of open files, default 1024
One NIC irq bound per CPU
Each NIC's TX queue length set to 20000 via ifconfig, default 100
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.core.netdev_max_backlog = 300000, number of unprocessed input packets before kernel starts dropping them, default 300
Kernel Parameters:
idle=poll, idle threads pool reschedule flag, default is to use HLT instruction
acpismp = force, use ACPI tables for processor information, default MP table

HTTP Software Notes
