Allowing for cache writeback delays, is the speed of direct-to-shared-disk
fast enough that using NFS as an "abstraction" layer would be faster than
any network extant?
Would it be as fast? would the effort to make this work exceed the cost
of making real networks exist?
It would seem that there might be opportunities to do 'cut through' in
the coding for known-private files after open (ok, inode allocation/extension
has problems) to optimize them to at-worst 'disk+bits' instead of NFS costs.
If one party mounts -r the FS (eg news spool) then does this reduce the
complexity? eg /usr mounted read-mostly for a bunch of tightly coupled boxes.
If some other protocol is used for interlock, does this make mmap shares
across clusters faster?
