I have had 3 SMP systems, and all have run DF. None of them have _EVER_ gotten an 80% speedup. The 2xP31.0Ghz got the best speedup; 1.4 on most positions. The 2xXP1.53Ghz gets the worst speedup; 1.25 (1.3 in my longer tests) on most positions. I don't know many people who use DF, but the ones I have talked to, get lousy results too.
