I am trying to gain an understanding of the kind of
performance Multibus II and VME backplanes actually deliver.
The claim is that MBII and VME get about 32Mbps.
However, when measured thru-put is quite a bit less
because of the software overhead in the case of MBII. Not being
as familiar with VME I don't think software over head is as big and issue
in that its shared memory vs. message passing.
In discussions I have had with others about this subject a better
metric would be to compare transactions per second from say a host
board to a network board over VME or MBII. This would be an apples to
apples type comparison.

What I am looking for are papers or any measured data available.
Has anyone measured the transaction per seconds accross MBII or VME?
What kind of real performance do hi-performance backplanes deliver
other than MBII or VME that are on the market today? What do machines that
are targeted at network server applications typically achieve.
