Testing Raspberry Pi network speed

Just got another Rapsberry Pi board. This time a 2.0 board (made in the UK!!). Anyway, doing a network (or USB, since the ethernet is via USB) stress test with the following command:

cat /dev/zero | ssh username@remotehost "cat > /dev/null"

That caused 100% CPU loading on the Raspberry Pi. Throughput is about 6MB per second.
