I've been using a chunksize of (2^)18 for most machines for a while; 
Optimization for smaller chunksizes could be done with better predictive 
prefetching but AFS development isn't my full time job and so I don't have 
that kind of time to spend on it.

100mb minimum, 2gb maximum, depending on what I'm doing with the machine.
