Notes

SUT Notes

APAR IY35693 was applied to AIX 5L V5.2
bindintcpu [interrupt level] [cpu] (Interrupt affinity - bind 4 Ethernet interrupts to 4 cpu's(1 interrupt to 1 cpu))
bindprocessor [processor] [cpu] (Process affinity - bind 4 Zeus child processes to 4 CPU's(1 process 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)
Disk layout: 1 disk for OS, 1 disk for webserver, 14 disks striped for file_set, 2 disks web logfile)
Set Gigabit Ethernet driver attribute rxdesc_que_sz=512 (set RX descriptor queue size, default=1024)
Set Gigabit Ethernet driver attribute rxbuf_pool_sz=512 (set Receive buffer pool size, default=1024)
Set Gigabit Ethernet driver attribute copy_bytes=256 (copy packet into contiguous buffer on transmit if this many or less bytes, default=2048)
no(network option) tuning:
no -o tcp_sendspace=65536(default socket send buffer size, default=16384)
no -o tcp_recvspace=65536(default socket receive buffer size, default=16384)
no -o somaxconn=10240(max listen backlog, default=1024)
no -o tcp_timewait=5(ensure that TIME_WAIT is at least 60 seconds, default=1)
no -o tcp_newreno=0 (disables the modification to TCP's Fast Recovery algorithm as described in RFC 2582, default=1)
no -o tcp_inpcb_hashtab_siz=128021 (increase TCP PCB hash table size, default=24499)
SCM stands for Single Chip Module

HTTP API Notes

no -o tcp_recvspace=65536(default socket receive buffer size, default=16384)
AIX (thread-scheduling option) tuning:
AIXTHREAD_SCOPE=S (AIX pthread environment variable, set all threads have system based contention scope, {1:1}, default=P{8:1})
AIXTHREAD_SLPRATIO=1:1 (AIX pthread environment variable, controls the number of kernel threads that should be held in reserve for sleeping threads, default={12:1})
