We recently upgraded a network of 41 turbo machines (monos) to 3.0, and  
are having SERIOUS performance problems.  When large numbers of people log  
in at the same time, it takes up to fifteen minutes for them to get  
Mathematica launched.  This is at least 3 times slower than the same  
operation under 2.2.

It seems that every time a user logs in, the Workspace does its scan of  
application directories, services, etc.  Isn't it supposed to only do this  
the first time you log in, and cache it?

Each machine is mounting a couple directories from a single file server:  
/Users and /LocalApps.  The netinfo server is also the file server AND the  
mail server, but this was also the case under 2.2.  There is also a clone  
netinfo server.

Any ideas, hints, suggestions?  We've been instructed to upgrade the  
network to 2.2 if we can't find a solution soon :-).
