AFS and kerberos

[Volkmar Glauche]

Performance clearly depends on your data usage scheme... If your data is 
write-once-read-many, then AFS may actually help you quite a lot. In our 
environment (identical data is read approximately 5 times, but written 
only once) average performance for applications is better than NFS by a 
factor of 1.5-2. If your application does not read any data, but only 
produces new data, then NFS is clearly faster.
