Hi all!

This patch tries to implement the afsd default tuning parameters 
discussed in the thread starting at 
https://www.openafs.org/pipermail/openafs-devel/2005-May/012158.html

I took the liberty of adding chunksize-tuning to the memcache too, 
with the motivation that people using large memcaches usually wants 
better bulk performance too.

It seems to work for me using both disk cache and memcache of various 
sizes.

Comments are welcome.


/Nikke - with greetings from Hackathon 3
