Regarding the cache, was there any specific reason we
ended up with ten buckets per block? This puts the
number of Centry per bucket at 204 using 16K RBUFSIZE.
Using a 4K RBUFSIZE, what performance (dis)?advantages
are there in selecting the BKPERBLK scalar? Presumably
we want to maximize CEPERBK?
Cheers,
Sam
