Hi All,

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
I am using intel IA32 multi core cpu.
Do you have any idea about what can cause the 2us delay?

Thank you so much.
