   I just put verions 5.0 of the Columbia Appletalk Package (CAP) on our
VAX 11/750, and it is extraordinarily slow.  A 2.2 Mbyte file took 23
minutes to transfer from the vax to the mac via a Kinetics Fastpath 2.  We
had intended to back up our hard disks over the network, but it would take
about 10 hours to back up our 40 Mbytes, which is clearly outrageous.
This prompts me to ask two questions:

1) Is Tops this slow, too? I would suspect not.

2) Is there anyone out there with CAP experience who can help me figure out
   where the bottleneck is?

   Our equipment is a Kinetics Fastpath 2 that is fairly new, a Vax
   11/750, and Mac IIs. The macs have Appleshare v1.1

   Running the server in debug mode, I find that it goes along just fine for
   a while, spewing out messages, then stops for 30 seconds or more (sometimes
   much more). It has stopped in a select() call, which means it is waiting
   for I/O. When this happens the mac appears to be doing nothing, and I
   don't know any way to tell what is going on in the Fastpath. Eventually
   it recovers, proceeds for a while, and stops again.

   Running the server with the "-S 1" flag has little effect. Running the
   server on a Sun 3/280 doesn't help.

   Any suggestions out there? I suspect the Fastpath box has problems, but
   I don't know any way to monitor it. Does anyone know of a program that
   will watch the traffic on an Appletalk network?

   Thanks for any help you can give me!
