Hi,
i did my usual tests.
current:
req/s: 3898.20
variance: 0.84
current+diff:
req/s: 3928.80
variance: 0.45
With this diff the messurements have been much more stable. The
variance of the req/s
messurements is now a lot smaller. Also the performance has increased.
For the bandwidth/s case thi
Userland threads are preempt()'d when hogging a CPU or when processing

for an idle CPU and puts it on its run queue. That means the number of
involuntary context switch often result in a migration.
This is not a problem per s
