Mail/Print servers & performance

[Jeff Giacobbe]

Just a quick question:

configuration: Sun 4/360 with 32 megs ram, two 669 meg hard drives,
supports 10 diskless SLC's and 4 diskless 3/80's

What requires more 'overhead', being a print-server or a mail-server?

I may have the oportunity to let another server take on the job of either
print-server or mail-server and I was wondering which service has the
greater impact on overall performance.
