It would be a nice addition to the documentation to have some thorough
benchmark tests. Any particular ideas on what good tests would be? Maybe
even just a note in the FAQs with a suggestion on how tests could be run,
and asking for users to contribute, would yield some help from others. I
would imagine that there have been a few users who ran their own internal
tests before choosing a solution, if they were made aware of the interest in
gathering those results, they may volunteer that data.
