when i try to configure the Squid with hih-mem (1.5G RAM),
i used this parameters:

kernel:
options NMBCLUSTERS=1024
options NMBUFS=4096
# depend of your memory size:
options MAXDSIZ="(1228*1024*1024)"
options MAXSSIZ="(1228*1024*1024)"
options DFLDSIZ="(1024*1024*1024)"
# yes, i added 1.2 G mem to maxdsize and maxssize,
# but just added 1G to dfldsize

i builded kernel with these parameters.

then, i put these sysctl's to /boot/loader.conf:
kern.ipc.nmbclusters="16384"
kern.ipc.nmbufs="65536"
kern.ipc.maxfiles="2048"

in your squid conf you have to enable your cache_mem
size max half size of the kernel MAXDSIZE value.

it was on FreeBSD 4.8-4.9...

bye:
a.
