disk/kfs does cache the hard disc, but if you've got heaps
of physical memory (and why not) it might not be using
as much of it as you'd like.   i think it caps the cache at 2Mbytes.

the 4.3bsd figure is possibly misleading since it's quite likely to be reflecting
the time taken to copy from one part of memory to another,
with nothing much done with the disc.  i'd try a file that's much
bigger than physical memory.
