Yes, I agree the P4 and Athslon a different beasts but my understanding is that a lot of the PIII optimizations aren't included yet. Im sure that their are a number of optimizations that could be included to improve performance on multiple processors.
Re the OO v RAD comments, my comments were based on the blanket statement that OO in Delphi doesn't make sense without BOLD. Im sure there are lots of small (ish) Delphi apps out there with no real use of OO but that does not mean it is not possible (or beneficial) to do OO in Delphi without a tool like Bold. RAD and OO are not neccasarilily mutually exclusive concepts, If I can create a class that easily plugs in to a number of applications and reduces maintainability surely that is RAD?
