TonyG: Are you saying that 19 is your high value as that's not very high.
I don't think I have a problem on my laptop.
The test I posted in my thread works fine on my laptop and the results from your tests are intermittent with
normal values between 17-19. I suspect the 'higher' values in my case were background processes.
<edit> My other tests suggested it was the CLS/FLIP which causes the jump in cycletime.
