    Following are the performance figures for various Ethernet interfaces
including the DEBNI :

debni	330 i/o's per sec
debna	135
delqa	120
delua	100
deuna	 45

i/o =  4 block i/o (typical average in diskserving)

  These figures were presented during a lecture at the latest
DECUS Europe Symposium in Den HAAG ( the Netherlands).

  It was also stated that for the VAX 85x0 series for example
the DEBNA is the limiting resource for MSCP disk serving.
If you upgrade to a DEBNI the VAX CPU (possibly) becomes the bottleneck
for MSCP disk serving...
