Based on my quick&dirty testing (the eventpos.pl and the input file xaa from the bug id #20218), on Tru64, with cc -O4, this claws us back almost to the 5.6.1 speeds (execution speed 5.6.1 = 100, maint branch after this patch = 117). I'll do some further profiling to see where's the rest going. (Unfortunately it seems that reverting the second-most-slowing-down change #14920 that did cause a 40% drop (IIRC) back in between 5.7.2 and 5.7.3 doesn't give us back much, if any, of the speed.) -- Jarkko Hietaniemi <jhi@iki.fi> http://www.iki.fi/jhi/ "There is this special biologist word we use for 'stable'.
