[OpenAFS] Speed of release or incremental release (replication)?

I'd like to have the most important volumes replicated, but as it
is today, even twice a day is to much hassle (it locks up during
release).

This means that 146 Kb was released per second

It say 'This is a complete release of the volume' so this leads
me to think that it should be possible to do a 'non-complete'
(ie, incremental) release... ?

And 146Kb/sec seems HORRIBLE to me! This is from one partition
(ie, disk) to another. No 'network connection' is done. I do
know that AFS in it self is through the network layer so some
overhead is expected, but that much!?

I MUST have configured something wrong, because I can't believe
that AFS is this slow!!


The machine is a dual PII 333MHz with Ultra160 disks 'in full
working order'... The machine IS loaded, but not that much...
