I've certainly heard anecdotal evidence along these lines, and it
certainly has been the case that in projects with which I've been
involved recently, the M based systems do seem to outpace Oracle.
What I have NOT seen is a rigorous study showing that this is indeed
the case. I suspect that, when you get right down to it, the question
ought to be "faster for what?" M based systems certainly do appear to
highly optimized for the ways in which they are typically used (a
good thing), but I have to wonder whether or not we good get
relational systems to outpace M based systems by choosing appropriate
benchmarks, too.
It is far from obvious to me how the two types of systems can
adequately and fairly be compared. My hunch is that the answer to the
question being posed here will depend to some extent on the
application domain.

that's true. I just got done writing an HL7 data access object to

the HDR which is Oracle. (Don't ask why I'm talking HL7 to an Oracle
database, I'm not sure I know myself.) I will certainly be looking
at the
speed.
