I've attached a revision of exactly the same benchmark run to get the
results in results_server.ods .

You'll see very similar figures to results_server.ods for HEAD and for
my patch, as you'd expect. I think the results speak for themselves. I
maintain that we should use specialisations - that's where most of the
benefit is to be found.
