About Informix, does any one Good luck. : have any experience with Informix OnLine running on 1 cpu, 2 cpu's or : 4 cpu's. I have heard that 2 cpu's and Informix OnLine 7.xx runs slower : than if it runs on a single cpu. Is there something about this rumour?. : Thanks. : Bjarne W. Jensen -- Alm. Brand Denmark No, that is not true. What is true is that the engine will run slower on a two processor machine if you set MULTIPROCESSOR to 1 (true) and SINGLE_CPU_VP to 0 (false) than if you had set MULTIPROCESSOR to 0 (false) and SINGLE_CPU_VP to 1 (true). IOW, it is slower on a two processor machine to configure the engine for multiprocessing than it is to just tell the engine you only have one.
