Notes/Tuning information
SUT Notes
Each node has OS on first disk; 2-disk RAID0 stripe for access log and file set
Each node had each interface connected to the PowerConnect switch
Nodes used ntpd to synchronize time to a central clock
Second node accessed first node's User.Personality, Custom.Ads, post.log via NFS
Operating System Notes
ulimit -n 10000, sets number of open files, default 1024
Each NIC's TX queue length set to 40000 via ifconfig, default 100
Each NIC's InterruptThrottleRate set to 3000 via modprobe, default 1
File systems mounted with "noatime,nodiratime,noacl", no inode access time updating, no access control lists
net.ipv4.tcp_timestamps = 0, turns TCP timestamp support off, default on
