HTTP Software Notes

Zeus Tuning Values:
cache_files 60000 (cache up to 60,000 files)
cache_max_bytes 0 (do not limit total size of cache)
cache_small_file 0 (keep any file no matter how small)
cache_large_file 1048576 (keep any file less than 1MB)
cache_stat_expire 864000 (check for file updates daily)
cache_flush_interval 864000 (flush cached files daily)
sendfile yes (use the HP-UX sendfile system call)
sendfile_reservefd 30001 (keep lots of descriptors available for sendfile)
sendfile_minsize 0 (no file is too small for a sendfile)
listen_queue_size 8192 (allow more connections to queue)
timeout 7200 (don't give up on a client easily)
keepalive_max -1 (no limit on number of keepalive connections)
unique_bind yes (dedicate one listener to each listed ip addr.)
bind_any no (don't bind the listen socket to IN_ADDR_ANY)
Zeus Site Configuration:
modules!stats!enabled no (don't bother to measure statistics)
modules!nsapi!enabled no (don't need any NSAPI support)
modules!isapi!enabled yes (we do rely on the ISAPI features)
modules!fastcgi!enabled yes (support the FastCGI interface)
Zeus Installation Notes:
Set LargePage attribute on all Zeus binaries [chatr +pi 16M +pd 16M]

HTTP API Notes

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

Software Notes

Network Notes

All Clients wired via 100BT to one of two HP ProCurve 1600s
SUT wired to a 1000-SX module within each HP ProCurve 1600

Client Notes

Client's HP-UX Parameters:
ncallout 5000 (increase number of potential pending items)
max_thread_proc 800 (allow more threads per process)
