FreeBSD 6.2, pentium 4 2GB RAM (but RAM is more than enough), 2 squid
disks, 3 directories.
request rate - will have to check when traffic is highest (somewhat like
50-100), 850 people network,

Trying to mount root from ufs:ad0a
SMP turned off, most FreeBSD users advice Hyperthreading works best
when... unused but i can try SMP.
squid config (other things removed, most important things only, acl's not
very complicated) below:
max_open_disk_fds 0
cache_swap_low 98
cache_swap_high 100
cache_mem 64 MB
maximum_object_size_in_memory 64 KB
maximum_object_size 10000000 KB
shutdown_lifetime 15 seconds
client_lifetime 2 hour
cache_dir diskd /squid/ad6a 50000 128 256 max-size=65536
cache_dir diskd /squid/ad6e 90000 16 256
cache_dir diskd /squid/ad2 180000 16 256
disk load are like 20%, CPU like 50% under highest load, system disk are
separate.
