To clarify and expand this: they are IBM Netfinity 5600 servers. 2 x
600MHz Intel P3 processors, 1GB RAM, and 6 x 18GB SCSI-160 10,000 RPM
drives in a RAID 5 array with an IBM ServeRAID hardware RAID controller.
The systems are old and (processor) slow, but the disk performance is
really pretty good, even today: it'll easily saturate GigE.
My point for this: CPU power matters little on the client side. RAM
matters, but only once you have enough: depending on the number of files,
the amount of RAM you truly need is literally in the hundreds of
megabytes. What *really* matters is I/O and network throughput--and on
any halfway-decent server with multiple high-RPM hard drives, you will be
limited by network bandwidth more than anything else.
