                                Network Notes

<> ATM MTU=9180 & Jumbo Frame Gigabit MTU=9000
<> 1 client per ATM network & 2 clients per Jumbo Frame Gigabit network

                                 Other Notes

<> server no (network option) tuning:
<> no -o sb_max=262144 (max buffer size allowed for a socket, default=65536)
<> no -o somaxconn=8192 (max listen backlog, default=1024)
<> no -o nbc_max_cache=100000 (max file size for network buffer cache, default=1048576)
<> no -o nbc_seg_limit=10000 (number of entry allowed in private segment, default=0)
<> 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)
<> Bind FRCA logging thread to CPU 0
<> FRCA logging - BINARY
<> Processor affinity - bind 4 ATM & 4 Ethernet interrupts to 4 CPUs ( 1 ATM & 1 Ethernet interrupts to CPU 0-3 )
<> 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.
