Can Parallel Programming Improve Performance

I love to optimize my code for performance, whenever I can.
So I wrote a simple speed test to see what works best.

I've use the new System.Threading, provided in the Parallel Extensions June 08 CTP from Microsoft and I have to said it is bloody awesome.

For example a simple for / foreach loop:

for (var item = 0; item < list.Length; item++)

foreach (var item in list)

This is the same example, but using a parallel for / foreach loop:
Parallel.For(0, list.Length, item => { DoSomeWork(); });

Parallel.ForEach(list, DoSomeWork);

Coding it is as easy as pie, it makes use of all the cores that your CPU has to offer.

Speed Test

Please let me know if this helps you.
