performance) was applied to AIX 5L V5.2 bindintcpu [interrupt level] [cpu] (Interrupt affinity - bind 8 Ethernet interrupts to 4 cpu's(2 interrupts to 1 cpu)) maxpgahead=64(the maximum number of pages to be read ahead,default=8) minperm=5%(the point below which the page-stealer will steal file of computational pages,default=20%) maxperm=95%(the point above which the page stealing algorithm steals only file page,default=80%) 4 different logs for 4 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, 14 disks striped for file_set, 6 disks striped for web logfile) Set Gigabit Ethernet driver attribute rxbuf_pool_sz=2048 (set Receive buffer pool size, default=1024) Set Gigabit Ethernet driver attribute txdesc_que_sz=1024 (set Transmit descriptor queue size, default=512) Set Gigabit Ethernet driver attribute copy_bytes=256 (copy packet into contiguous buffer on transmit if this many or less bytes, defult=2048) Set Gigabit Ethernet driver attribute intr_rate=2000 (maximum number of receive interrupts per second that a Gb ethernet adapter will generate, default=0 (no limit)) frcactrl pctonintr 100 (frca set to allow 100% cpu time on interrupt, default=90) frcactrl revaltimeout 100000 (set frca revalidation timeout to
