[OpenAFS] recommended UFS parameters for cache partition?

[Benjamin Kaduk]

Hi all,

Setting up a new solaris machine, I've gone and partitioned the disk, 
giving about 9GB to the cache partition.  But now I need to put a (UFS) 
filesystem on it, and I wondered -- should I be tweaking the UFS 
parameters for the CM's workload?  It seems like the filesystem's 
structure is pretty well-determined, with a bunch of chunksize (?) files, 
the number of which is determined by the arguments to afsd.
So, if I know what my afsd settings are, how does that translate to an 
optimal UFS layout?
(Or should I just not worry about it and assume that any potential 
improvements would be lost in the noise?)

Thanks,

Ben Kaduk
