Bob is still very impressed by the nodes a second from some old and dusted alpha processor somewhere around 2000. Time to run a bench at crafty 16.19. Please remember this thing is compiled somewhere in 2000 if i guess well. Compiler for K7 is like 30% faster nowadays in nodes a second: This is a very slow mainboard (thunder K7) to test it. I didn't even do effort to compile it reorder it with learning and then run again. Already raw nodes a second is like 1.2MLN nodes a second nearly *without* any tuning yet! That's pretty much faster than todays crafty Bob! The fastest alpha in these days only got 1.5MLN nodes a second at a dual. If i go tune this thing recompile it for SMP with all kind of profile info, and kick out some outdated assembly, then i'll hit 3.0 MLN nodes a second quickly!
