Hi Hartmut
> Is this the best performance that can be expected from ARM7/9 platforms?
Look there
https://www.osadl.org/Latency-plot-of-system-in-rack-2-slot.qa-latencyplot-r2s3.0.html
There are also other OMAP devices in the nice testrack of the OSADL guys.
Further i would suppose to switch of power management (look also for the cpu idle stuff).
The advanced power saving mechanisms can create some unwanted latency.
Best regards
Tim
