Software needs to explcitly support 2 or 4 cores, else one and the same workload of one core only gets equzally distriubuted amongst the avialable cores. Instread mof one core being on duty to 80% you then have 4 cores each of them being busy at 20%. To have all four cores running at 80% and getting the speed boost from that, you need softweare supporting that.
Thnat'S why modewrn chess engines nowadays get released in two versions: single core versions at around 40-50 Euros, and multiple core versions at around 80-100 Euros. Its the same engine, but optimised for several cores.
FS9 is single core only. You cannot get around that. You only get a GHz-independant speed boost from the fact that two processors for example allow you to have one CPU running Windows and background tasks, leaving the other free for fully calculating in the service of FS9.
That's why I prefer 2 high GHz processors over 4 CPUs with lower GHz.
