Which answer should I accept?
I have asked this question: Why is my AsOrdered PLINQ query faster than my unordered one and got two very good answers.
They gave me leads to investigate I hadn't though about, and since one of them (plus another person in the comment) reproduced my code without seeing the effect I observed, I am lead to believe that it may be due to a difference in hardware.
Something that people can very difficultly diagnose from a distance.
The main thing however is that I do not have any certain answer to my initial question: "Why is my ordered plinq query faster than the unordered one?".
What should I do? Not accept an answer since I don't have a definitive answer and that the posters didn't explicitly say in their answer text : "barring all my other suggestions it is probably an hardware or implementation problem".
Or should I give the accepted answer to the person who most helped me trying to find an explanation for something they possibly can't pinpoint for certain without access to my machine.
There is also the possibility that there is an answer that someone could give me but no one has done so, but that doesn't seem so certain at this time.
This would seem like a good situation for a bounty except for my low reputation (at the time of this writing) and the fact that my question isn't related to work or a personal project (just me mucking around one night).
