Hello!
I of course know that Linux is not running in real time and that some resources are needed for things in the background and for the graphical overlay.
However for example the speed remains the same when I connect via UART to Linux and dont use the graphical interface and it is disconnected.

Still I am wondering why I can only achieve about 300kHz when the CPU itself should be running at 900MHz ?
This is feeling way to slow in my opinion.

Also I do not have a Nios II processor or any possibility to get one so this in no option.
