SPEED UP SLOWNESS ON 700, 701 MODELS
Short version

sudo apt-get install cpufrequtils

p4-clockmod < (add this line to the bottom of you /etc/modules file)
/usr/bin/cpufreq-set -d 675MHz -u 900MHz -g ondemand < (add this above “exit 0” in /etc/rc.local)
restart
Explanation

The CPU in crunchee uses an “OnDemand” governor which has problems with non-Atom processors. Therefore, the cpu clock speed by default is set to 113MHz (type cpufreq-info to see for yourself) which is why the CPU usage is so high yet the system runs so sluggishly.

Adding the line “p4-clockmod” into your /etc/modules file ensures that the manual clocking module is loaded automatically.

Now you want to make sure that the settings you like are set upon boot. For that you add the call to ”/usr/bin/cpufreq-set” in /etc/rc.local. You need to do this before the “exit 0” statement.

/usr/bin/cpufreq-set -d 113MHz -u 900MHz -g ondemand exit 0

This means the CPU can vary between 133MHz (-d indicates lowest speed) and 900MHz (-u indicates highest speed). Ondemand specifies that the powermanagement should look at my usage. I’m doing nothing? Run at 133MHz, I’m watching youtube? Run at 900MHz.

In order to vary between 600MHz and 900MHz:

/usr/bin/cpufreq-set -d 675MHz -u 900MHz -g ondemand exit 0
