Yes.

lon-capa loves CPUs the more CPUs the more simultaneous users you can
support.

We have a couple of dual core dual processor machines in use at MSU
(and soon will have one quad processor, dual core machine)

Scaling of number of simultatneous apache processes is (not
suprisingly) fairly linear. (4 total cores can serve ~4 times as many
pages per second)
