Maybe it is time to define a unit of measure.

Hi Joe,
I recently posted these links elsewhere, but maybe you (and others?)
will find them interesting:
A talk by Barry Bolding of IBM's Deep Computing group about Cell:

A paper out of LBNL's Future Technologies Group on C

If this has already been discussed on the list, a pointer
to the thread would be appreciated!
Looking over the list I found a couple references to the
IBM cell processors being used in PS3. Has anyone had a
chance to actually use/test one of these systems yet?
Considering that the PS3 is supp

Could it be that you are getting timeouts because you don't have
enough nfsd daemons. This only might happen under heavy I/O load. And
when there are thousands of operations floading the server sometimes
it just has to drop some off the queue when the queue get full.

No, but I can show you a series of slides with performance compared to
