Quote:

When parallelizing any code, including loops, one important goal is to utilize the processors as much as possible without over parallelizing to the point where the overhead for parallel processing negates any performance benefits. In this particular example, only the outer loop is parallelized because there is not very much work performed in the inner loop. The combination of a small amount of work and undesirable cache effects can result in performance degradation in nested parallel loops. Therefore, parallelizing the outer loop only is the best way to maximize the benefits of concurrency on most systems.

ConcurrentBag list = new ConcurrentBag();
ParallelOptions options= new ParallelOptions { MaxDegreeOfParallelism = 2 };
Parallel.For(0,10000, options, item => 
{
 list.Add(item);
}
