What units of measure should one use in evaluating an OSI 
implementation?  Are the old units such as elapsed time, bits per second 
and so on sufficient?  I've read some of the derisive comments here 
about the expected poor performance.  I'd be very interested in any 
actual experiences and examples of performance measurement.  Does anyone 
know if any of the voluntary test labs or interoperability test 
facilities provide this kind of information? Is there any hard data on 
the comparison of X.400 and FTAM in moving files of different sizes?  
I've heard people comment that for short messages, the overhead of X.400 
is extreme.  Does it remain so regardless of file/message size or is 
there a break-even point? 

This is my first posting here and conditionally apologize if I've committed 
any network transgression.  At any rate, I would appreciate anyone's 
assistance and thank you in advance for same.

Best Regards,
David Love
