Hell,
in appreciation of the work that has been done by the -rt team I would
like to share my (first) test results on a PowerPC e300c3 core @ 400
MHz, using the Freescale MPC8315E SoC (boot log at the end).
The test is suboptimal because I am testing through a 100 Mbit/s
Ethernet switch. I will follow-up with results from a 1 Gbp/s flood
ping stress later.

Ping flood from host (active during test):
sudo ping -l100 -f 192.168.1.100
Wakeup latency test using cyclictest:
root@mpc8315e-rdb:~# cyclictest -t 7 -n -p 70 -l 10000 -q
T: 0 ( 2254) P:70 I:1000 C: 10000 Min: 22 Act: 54 Avg: 51 Max: 101
The host reports zero packet loss. Note this is through a 100
MBit/seconds pipe, so we are not really stressing the target.
leon@witty:~/sandbox/mpc8313e/openembedded/org.openembedded.dev$ sudo
ping -l100 -f 192.168.1.100
