I think consumed resources (CPU cycles, memory, disk I/O, electricity)
might become interesting when it comes to compare different MTAs for
a high volume scenario on a server at some cloud service provider.
(depending on the cost model those providers are using to calculate
their billing of course).
I believe: It will be very difficult to construct a realistic
MTA-benchmark suite with reproducible results. There are way too
many different interacting factors.

What kind of information do you expect?
