Other Notes

server no (network option) tuning:
no -o sb_max=262144 (max buffer size allowed for a socket, default=65535)
no -o somaxconn=16384 (max listen backlog, default=1024)
no -o tcp_sendspace=28000 (default socket send buffer size, default=16384)
no -o tcp_recvspace=28000 (default socket receive buffer size, default=16384)
no -o tcp_timewait=5 (ensure that TIME_WAIT is at least 60 seconds, default=1)
no -o nbc_limit=393216 (max network buffer cache, default=786432)
no -o nbc_max_cache=60000 (max file size for network buffer cache, default=131072)
no -o nbc_pseg=80000 (number of entry allowed in private segment, default=0)
bind frca logging thread to cpu 0
frca set to allow 95% cpu time on interrupt
frca set to run without virtual host support
processor affinity - bind each jumbo frame network intr to a cpu
12 httpd.conf used each binds to an ip address, minserver=5, maxserver=10
client no (network option) tuning:
no -o tcp_sendspace=28000 (default socket send buffer size, default=16384)
no -o tcp_recvspace=28000 (default socket receive buffer size, default=16384)
no -o delayack=3 (delay ack for connection setup and shutdown, default=0)
no -o delayackports={80} (delay ack ports, default={})
Alternate HTTP/HT.c used. Repeated client-side calls 'gethostbyname()' ommitted, as approved by SPEC. No change in measured server performance but reduction in client load.
