Hello

   I'm working on solving an AFS issue that has been a problem at my
employer before I arrived here.  Performance in general has been poor,
much slower than NFS. I ran bonnie++ to check this out and apparently
read/write performance was not bad, it was file creation, deletion and
renaming that took forever.  Looking further this was do to the fact
when transactions like this are done, it invalidates the cache, so the
filesystem must be reread.  When you are in a software development
environment this is a problem.  Engineers checking out an entire trunk
to their AFS home would take FOREVER.  So digging further it appears
that code Has been added to improve performance.  We are running an old
version of AFS.. 1.4.1.   Are there any configuration differences
between 1.4.1 and 1.5.7?

Is there a FAQ posted regarding the upgrade?    Can I have a mixed
environment of versions?  I'd like to update my replication servers
first and run some tests

Before I upgrade all the servers in the cell.

Thanks.
