Hi and thx for your reply.
The work is inhomegeneous, so the result of the experiment will surely show an increase of performance using 2*N threads.

That is the current number of threads I am using : #threads := c * #Physical Processors
where c is a constant that compensates for the non-zero probability that a thread could be in a blocking state within the task.

Exceeding this limit, will show a decrease of performance due to context switching.

My specific concern is with virtualized environment where most of our application execute nowadays.
The guest system is often allowed to "see" less processors than the host : I expect this to be true then :
#Physical Processors > #Logical Processors

Thus the c * #Physical Processors limit will exceed the actual number of threads that the system can actually execute in //.
