Hi Craig,
We have a 802.15.4 transceiver that is capable of 250kbps. We are
thinking of using this with a Cortex M0+ but wanted to make sure that
the M0+ would have the processing power to handle the
802.15.4/6lowpan/ipv6 stack at a datarate of 250kbps.
I just wondered if anyone had done any datarate measurements on existing
development boards using the Cortex M0+?

Hi Simon,
Throughput will be highly dependent upon the RF environment and what
transceiver you are using. The M0+ most likely has enough power to do
it under ideal conditions, but retransmissions due to collisions will
limit the effective bandwidth.
You can use 900 mhz and 2.4 ghz transceivers with 15.4. ~900 is
significantly less crowded but lower theoretical bandwidth. The Atmel
212B is 900 Mhz and specs 1000 kbps as the max air data rate.
Which transceiver are you using?

Has anyone done any performance tests to see what throughput can
be achieved using RIOT?
I would be interested to know if the Cortex M0+ is powerful enough
to sustain 250Kb/s TCP over 6lowpan/802.15.4.
Does RIOT have any mechanism to measure CPU usage?
