Yeah, the implementation in the C series is very slow, not even Ultra33,
hence the really high CPU utilization.

Unfortunately both PCI slots are filled with NIC cards. I was always under
the impression that the Mesh chip did 10MB/S. Is this true? The boot message
says:
mesh0 at obio0 offset 0x10000 irq 12: 50MHz, SCSI ID 7

Thanks for the info, Chris. It looks like I'll just let it spin all the
time, maybe turn it off at night.
On a slightly unrelated note, I may get my hands on a SparcClassic. Anybody
have any ideas how this would do as an Appletalk server (with the Barracuca)
vs. the C500/200?
cheers,
Matthew
