Very high shfs CPU usage! -> Turns out my speed governor isn't working!

Recommended Posts



Found out why my speeds were being so hopeless now.


go script:


/sbin/modprobe powernow-k8

/sbin/modprobe cpufreq_ondemand

for config_file in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do

    echo ondemand >$config_file



When this is enabled, speeds drop to either 800/1200/2400/3000Mhz.


Now when it's transcoding it jumps up to 3000mhz, but when I'm transferring files, it doesn't sit at 3000mhz and limits my transfer speeds.


When it's set at:

ondemand: 10-30MB/sec

performance: 50+MB/sec!


Why is PS3MS hitting 3000mhz and shfs isn't!?


Any help would be great, I'm going to leave it in performance mode until I can get speedstep back :(

Edit: Nevermind!


Some testing:


Left picture is to a cache drive enabled share, right picture is to a parity only share.


Speedup % is 60.


sampling_down_factor = 1



sampling_down_factor = 10



sampling_down_factor = 50



sampling_down_factor = 100



Max speed = performance mode



The drops are due to the NIC driver falling over :(
