for both CPUs to be 'ondemand' copy the 3 lines below (exactly as is) and paste 
 in webif page .../Diagnostics.asp and save as startup


for CPUFREQ in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do [ -f $CPUFREQ ] || continue; echo -n ondemand > $CPUFREQ; done
echo 35 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor


 like so:


    # # #
 of course you have to do a reboot for that to take effect
      OR
 you can open a ssh / telnet connection to the EA8500 ...if you do it this way best to:
 paste 1st line 'hit enter' paste next line 'hit enter' & paste 3rd line 'hit enter'
 
 takes effect imediately --- you can see the CPUs at 800 MHz on webif page  ../Status_Router.asp
 unless you got some wild stuff going on --- then 1 or both may be still at 1400 MHz
 
 the 2nd & 3rd lines just tell the CPUs when to do their thang and these I have listed are very good for that   :-)
