Do you use those machines for something different than SQUID? Squid won't
take big advantage of 2 CPUs, unless you are running 2 squid copies, and
then you don't need each of them take more than 2GB of memory...

I am not sure if the FreeBSD system does allow process take more than 2GB
of RAM. IIRC, linux allows up to 2GB and there is patcvh for allowing 3GB,
but that is a hardware limit, caused by 32bit addressing on i386
architecture.
This might be the problem.
