I now have cpufrequtils installed on my debian and ubuntu servers ; the debian unit has a real hdmi display and has been my primary desktop workstation most of the summer. The ubuntu server is housed in the ABS box from Radio Shack and is being used as a headless server; I am accessing its desktop via VNC on my iMac. The debian does work ( GbE ) and the ubuntu does not work ( GbE ) but is connected via the same switch with the modified cable-- clicking along great at 100mb/s.
On irc today longsleep indicates that his kernel switches from 'ondemand' to 'interactive' automatically after 30 seconds. I found that this is not true ( not on my machines ) and that cpufreq-info shows 'ondemand' for both systems by default.
Its very hard on my working system to get consistent results ; one iperf run will get speeds in the mid 300s to high 300s one time, and will get high 200s to low 300s the next... without changing anything; however, I can confirm, after running iperf many times with each governor, that the speeds on average are somewhat higher with the 'interactive' governor. Its not dramatic, but more often than not the speeds were in the higher 300s to lower 400s with the 'interactive' governor; and typically on average in the mid 300s to lower 300s with the 'ondemand' governor.
