Dear Ed,

These last possibilities are almost certainly true, however accurate and
valuable your previous assertions were;-)

Amen, although I'm happy enough to provide a toplevel interface and/or
scripts to do the automation with if people use benchmaster...

But benchmaster almost certainly won't show any macro-advantages as it
is a micro-benchmark.  And macro benchmarks based on tools like mysql
are notoriously poor predictors of performance variations with anything
BUT the tool in question, if that (even though I used to read PC
Magazine "benchmarks" of just that sort for DOS and Windows boxes with
great amusement for many years).
