maxperm=95%(the point above which the page stealing algorithm steals only file page,default=80%)
16 different logs for 16 zeus instances (1 log per zeus instance) for dynamic requests
frca-log.N (once the frca-log.N reaches 1GB, a new frca-log.N+1 is generated) for static requests
Disk layout: 1 disk for OS, 1 disk for webserver, 20 disks striped for file_set, 3 disks striped for web logfile)
Zeus doc_root using JFS2; OS, webserver, weblog using JFS
Set Gigabit Ethernet driver attribute copy_bytes=256 (copy packet into contiguous buffer on transmit if this many or less bytes, defult=2048)
