Here I disagree: if a platform run ten times slower than another, why
not having a latency ten times bigger ?

Additionnaly, the latency depends on the kind of load put on the system
during the test. A user is expected to calibrate the nucleus latency of
his system under the particular load which is expected on his system.
We should add a page on the wiki about the latency calibration.
