Notes

SUT Notes

APAR IY28102 was applied to AIX 5L V5.1
bosdebug -H (enables secondary thread on the processor)
bindintcpu [interrupt level] [cpu] (Interrupt affinity - bind 8 Ethernet interrupts to 4 cpu's(2 interrupt to 1 cpu))
maxpgahead=32(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, 10 disks striped for file_set, 1 disks for web logfile)
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 large_send=yes (turn on large_send capability of TCPIP, default=no)
frcactrl pctonintr 100 (frca set to allow 100% cpu time on interrupt, default=90)
frcactrl revaltimeout 100000 (set frca revalidation timeout to 100,000 seconds, default=300 seconds)
no(network option) tuning:
no -o tcp_sendspace=131072(default socket send buffer size, default=16384)
no -o tcp_recvspace=65536(default socket receive buffer size, default=16384)
no -o send_file duration=100000(cached send_file expiration time, default=300)
no -o somaxconn=10240(max listen backlog, default=1024)
no -o nbc_max_cache=409600(max file size for network buffer cache, default=131072)
no -o nbc_pseg=800000(max file entries in private segment,default=0)
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)

HTTP API Notes

Zeus PEPP-06 SPECweb99 toolkit used for dynamic content
Compiled with IBM VAC 5.0.1
post.log in /weblog directory instead of doc_root

Client Notes

APAR IY17356 was applied to AIX 4.3.3
no (network option) tuning:
no -o delayack=3(delay ack for connection setup and shutdown,default=0)
no -o delayackports={80}(delay ack ports,default={} )
no -o tcp_timewait=5(ensure that TIME_WAIT is at least 60 seconds,default=1)
