Could you post some examples where Deep Shredder 5 is (significantly) better on single CPU, than Shredder 5? I have tried this comparison with 8 test positions, where Shredder 5 had needed mid-range solving times. I 5 of these, DS's result was within ±10%, one was better, two were worse. Do you have such data (equal/better/worse)? I'd like to decide if Shredder 5, or Deep Shredder 5 to use on single CPU... In general, if no important other improvements have been added, I would assume that the SMP version has a small overhead or something like this (additional, but useless code for single CPU operation) which results in a small disadvantage. Maybe SMP experts can acknowledge this, or tell that it's nonsense :o) ? Thanks, M.Scheidl
