On 12/21/1999 somewhere around the time of 19:07 +1300, Owen Watson spoke about "Is
1.5MB/min toooo sloow?":

Depends on the network, the tape drive being backed up to/computer doing the backing
up and what the P90 is doing or if it has any screwy network settings. 1.5 MB/min
seems a little slow but that may be what your setup does. I don't have any machines
that slow being backed up but for comparison I have a PII 366 over 10BT backed up to a
Sony DDS-3 SDT9000 and I get about 24 MB/min. I figure anything below 12-15 MB/min
and you should be looking around to see where the bottleneck is. I have another
machine, P150, that gets about 13 MB/min across the same network to the same drive but
the I know the bottleneck is the part of the network it is on (it's dirt slow
(sub-Localtalk speed)). That will be fixed once the 100BT network is up and running
and I should see a dramatic speed increase for that machine. The limitation will then
become the tape drive. When I compare speeds for the DDS-3 drive and a the DDS drive,
there is a great speed difference. I don't remember what the speed is that I get for
the DDS drive.
I'd start looking.
Hope this gives you some sort of direction. It's 3 am and I'm a little groggy.
