Well, if the penalty is order of 20% (as opposed to integer multiples)
I think the discussion is over. We're not going to introduce arguable
security holes for that sort of gain --- there are other places we could
find that much speedup for much less risk.
(BTW, were you testing CVS tip or 8.0? The recent COPY FROM speedup
patch would have affected this test.)
