Hi,
In the default setup i can see that eCos net background thread is put on
priority 7 and the "fast net" is set to run on prio 6. Can it be any
problem is i enable timeslicing and put them on the same priority? Do
they need to be run at separat priorities?
Regards, Daniel Lidsten

I think these values we determined from experiments. Having the fast
net thread higher than the background thread resulted in higher
network throughput. I believe it still works with them being the same,
but i think the performance drops. The actual values, 6 and 7, doesn't
matter. You could quite easily use 20 and 21, or 10 and 13 etc. Just
use what ever fits best with your other threads in the system.
