Cool question. About how about the number of gears on the bike. Allows it go faster — Yes. Will, if You personally to go faster on this bike — who the hell knows. If you plugging in the disk operations, then the point with the number of processors?

0), CPUs are much different
1) kernel especially are very much different. Compare the some bulldozer and Sandy Bridge
2) if performance depends only in the computational core and to assume that the computational ability of the kernel here and there equal the growth will be linear. The web server is one of the most easily scalable to large number of cores task
3) if rested in the base — you no the kernel will not help. Although it will be slightly better due to the fact that worker the web application will not delay on those 2 cores there is.

The commentators are absolutely right — it all depends on your site. Put some MERALCO consumption of resources, locate the bottleneck and think already what you need. So soon will be clear how to increase the performance, at least approximately.
Again, read the book of John Allspaw "the Art of capacity planning".
