What I really did was to go straight to asking the question:-)

Up to now I have two answers, or really caveats:
 - a varying blocksize implementation should have minimum effects   on performance for user of the default settings.
 - the said benchmark may not be that meaningful, so the performance   impact is to be accessed more thoroughly.

Yep. A 10% potential performance impact looks worth the investigation.
