Remember... compiling for an alpha will take necessarily longer than an intel to compile things. Alpha must generate more code (RISC) vs. the Intel compiles which are CISC.

It has to do with the fact that alpha doesn't have a built-in roll function, like the intel does. Go to www.distributed.net they JUST released some killer hack that speeds up the alpha code 1.5-2.0 times the old speed! I don't know WHAT they did, but it FLIES now!
