I am doubtful that the number of CPU or number of users (yes, I
know `maxusers' is currently used to compute the default
`nmbcluster'...) can be linked to any network load pattern at all. You
can have a 24 CPU machine made for 4096 users with a single NIC, not
requiring much memory, while a 1 CPU machine with only 1 users can
have +8 NIC and require a huge quantity of memory. Available KVM space
should also be taken into account, as it is rather limited on i386.
: even more today where you can have a huge number of virtual CPU.
