I actually have 2) and 3). 1) is easy to do, though.
Anyone can recommand some test programs to try?
A while back, I tried lmbench which is not very telling.
I think the reason is that most of the tests are not using

However I might try it again anyway. It might tell the
difference between 1) and 2)&3) easily.
