SUT Notes

APAR IY12051: New hardware support for Oct-2000
no(network option) tuning:
no -o send_file duration=180000(cached send_file expiration time, default=300)
no -o somaxconn=8192(max listen backlog, default=1024)
no -o nbc_max_cache=131072(max file size for network buffer cache,default=1048576)
no -o nbc_pseg=10000(max file entries in private segment,default=0)
no -o tcp_timewait=5(ensure that TIME_WAIT is at least 60 seconds, default=1)
Interrupt affinity - bind 4 Ethernet interrupts to 4 cpu's(1 interrupt to 1 cpu)
maxpgahead=64(the maximum number of pages to be read ahead,default=8)
maxfree=184(the number of frames on the free list at which page stealing is to stop,default=128)
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%)
Rotate log every 30 minutes
1 disk for OS and webserver, 2 disks for file_set, and 1 disk for logs
2 switches are chained to handle 3 nets. Another switch handles the 4th net
4 clients per net

HTTP API Notes

Zeus ISAPI interface used for dynamic content
FastCGI used as communication method to manage all the independent CGI processes

Client Notes

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)
