Hi,

My question is if you have a system (or server) with 4 CPU's all running at 500mhz EACH how does the OS use this? Does this mean I have 2.0Ghz processing power? 500mhz x 4CPUs = 2000mhz??

"Does this mean I have 2.0Ghz processing power?"

No, it means you have 500MHz processing power. The 4 CPUs are not combined. Also, having 4 CPUs is not the same as having a quad core CPU.

OK so I have 500mhz power, are the other 3 just used for redundancy? Or does it get load balanced between all 4 CPUs? I cant draw 2000mhz to one aplication but can I draw 500mhz each to each of the 4 applications (assuming os power excluded)

Well put. The max that can be used by any one app is 500MHz.

WOW that makes good sense. But why? How would a server need that many small aplications running? 1CPU for OS, CPU2 for server applications.... is CPU3 and 4 just redundant?

Its far from modern Its a ProLaint 5500 with 2GB ram and quad Xeons all four are 500mhz P3's. Its a relyable brick.
