It depends on how big is the address space for your machines.
32-bit machines can address 4GB of memory, so it's reasonable to use 2
or 3 times the amount of RAM space (if you hawe 256MB or 512MB - the
swap should be 768MB or 1GB), but if you have 32bit machines with 4GB
of memory there is no need to use more than 4GB for swap.
64-bit machines can address 2^64 bytes which is a very big address
space, so you should use the guidelines in the documentation (FreeBSD
