What's the advange of a dual CPU server?

The expansion into a dynamic operation seems to be all the rage these days, and rightly so. Allowing information to be pulled from databases and provided to the end user (visitor/customer) is very important. The functionality of the dual CPU actually works like an extra set of tires on a truck. You've often seen a dump truck on the road hauling trash. Some have only 1 set of tires at the back, and some have 2 sets. The extra set of tires allows for added traction and distribution of weight.

A dual CPU operates in the same way. It allows you to not only have "one set of tires on the ground" but "two sets" allowing less load to be placed on any single set. Esentially this means that if one CPU is busy doing something, another CPU can assist. You're really spreading the power over TWO CPUs and getting TWO brains to work to solve an issue quickly. The more CPUs you have, the faster processes can be preformed.

Normally you wouldn't assign one CPU to do one task, and another CPU to do another task. Dual CPUs in a server environment are generally used to run in parallel.  Both CPUs sharing the workload.

A Dual Core CPU operates in much the same way as a Dual CPU system would.
