Now I am testing the response time in Fiasco, especially for the worse case. The results are strange. The worse case result are always around 2us. I have filtered out the timer interrupt, so I cannot understand what happened. I am using intel IA32 multi core cpu. Do you have any idea about what can cause the 2us delay?
For worst case, 2µs does not seem bad to me for this type of CPU. How did you try to get the worst case (or do you mean something different with 'worse case'?)?
