stack on server very very slow

Hello Phil

thanks for your hint. In this case, the save command works speedy.  
Only stackoperations
take very long. There is a lot of text-processing going on, on many  
fields on many cards.
What surprises me, is exactly this: Why should this take longer than  
with the local stack?
Both, local, as remote, stack should be processed in memory. As the  
RunRev manual states.

-> But: if a stack is sucked in clients memory on opening - then  
there should not be a speed
issue for me. So there is some sort of communication to the remote  
stack. I can see it
on my network gauge!

Client and server are both running OS X 10.4.2, so its using AFS,  
Apple File Sharing.

Yes, it seems, that there is some sort of failure, hope we can track  
this down.
(Tested my AFS connection with other applications. Those have no  
speed issue).

Kind regards

Andreas Stämpfli
