Description Karol Gwaj 2012-11-22 10:54:47 EST
Looks like default value for TaskScheduler.MaximumConcurrencyLevel is different
between MS.NET and Mono:
MONO: TaskScheduler.MaximumConcurrencyLevel == <processors count>
MS.NET: TaskScheduler.MaximumConcurrencyLevel == int.MaxValue

it is making difference, because Mono methods on Parallel class (ForEach,
Invoke, ...) in some cases execute much slower than in MS.NET (if you specify
parallelizm level greater than number of processors)
