Hello,
i86 pentium 4 Fujitsu siemens scenic E600 :
with ubuntu 10.04 and 2.7 linuxcnc
*latency +/- 22,000 max*
I format the pc and i install debian 7 and 2.7 linuxcnc
*latency +/- 65,000 max*
Why do you have an idea?
Best regards,
Pierre

Yes, the D525MW is supposed to have a normal power draw of 13 W,

specifically which version?
I have a D525MW and get much better results

snipping off previous discussion now i have tested: boot with isolcpu(big
improvement in general latency but still spikes)
turn of smi, (improvement in general latency but still spikes)
'idle=poll' and 'nohlt'(little or no effect)
acpi = off and api=off

when runnnig latencytest and 3 x glxgears + some video i can run for 30

I am running 10.04 LTS and LinuxCNC 2.5.2
when you say, boot the kernel with the option 'idle=poll' is this done
the same way as isolcpu?
yes
try both 'idle=poll' and 'nohlt'
