Subject: crafty 16.19 speed

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kind of profile info, and kick out some outdated assembly, then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!
