We learned rather quickly that several of the commands in /usr/afsws had

Hi Jeff,
That makes sense. Our experience is different: in nearly two years
of running a cell we have not had a server outage hit us like that
(must be just around the corner! :-).
I would contend that if you make /afs/@cell/@sys/usr/afsws highly
available (ie lots of servers and replicated ReadOnly copies) then
you can achieve the reliability. There is some performance gain in
placing replicated RO copies on servers "close" (ie same LAN) to
the clients.
In our (small cell) environment, reliability and "manageability"
(ie simple distribution) outweigh small (?) performance gains.
We achieve better client performance by using RAM cache when possible.
One box has a 256MB RAM cache and it really "zips" along!
