I'm running a vanilla master build with software flow offloading, and I noticed that the CPU wasn't running at its fastest frequency while benchmarking WAN<->LAN. Speeds consistently topped out at 600Mbps on a gigabit link.
| Governor | Consistent Speed | Power Consumption while idle |
|---|---|---|
| ondemand (default) | ~600 Mbps | <= 6.9W |
| ondemand (tweaked) | ~850Mbps | <= 6.9W |
| performance | ~850Mbps | >= 6.9W |
Tweaked settings for ondemand scheduler:
echo 35 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor
Hope this helps.
