difference in performance it would be possible to obtain with VMS. With VMS
you're dealing with ODS2, DECnet and the Clustering software, on Unix you've
got ffs (or whatever the filesystem BSD is using), TCP/IP and NFS. On the
downside, Unix tends to beat VMS at disk IO, still we're talking more the
difference between a RQDX3/RD54 combo vs. a nice fast more modern server
with SCSI (or IDE) disks.
I'd say it's more the difference between the throughput of the DEQNA
and the throughput of the RQDX3/RD54 than it is between the difference
between MFM & modern SCSI. My fileserver will spew data a good bit
faster than the DEQNA can process it. The Qbus ethernet is the
bottleneck.
No hurry, anyhow. It's mostly academic to me - the whine of the MFM
drives makes SWMBO nuts. The choice to go network-based storage had the
unexpected speed boost, but peace in the castle was/is the overriding
factor....
