Intellectual honesty? Wish I would be seeing it. So far there is not even
the uptake required on your side to discuss the problem.

There is no threshold. HPC and other industries want processors as
a whole with all their abilities. They will squeeze the last bit of
performance out of them.

Ok so you are saying that the reduction of OS latencies will make the
processor completely available and have no disturbances like OFFLINE scheduling?

Peter has not given a solution to the problem. Nor have you.
