My kernel settings

Script and Conf can be taken from here

Voltage settings:

:XLV is: "30 20 30 33 38 38 45 45 48 48 54 54 60 67 72"
:ideal: 30 30 30 30 33 38 45 45 48 48 54 54 60 67 72 (first three ignored)
:ULV: 25 25 25 33 38 38 45 45 48 48 54 54 60 67 72
:LV: 30 30 38 48 48 54 54 54 54 54 54 54 60 67 72

Analyzing time_in_state (by rooted) - rev4

#!/bin/sh

idlefreq=`awk '{if ($2 > 0) print $1}' /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state | tail -n 1`

tis2=`awk '$1 == "'"$idlefreq"'" {idle = $2} {sum += $2} END {print sum-idle}' /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state`

awk '{print "\nCurrent frequency: "$1/1000" MHz\n"}' /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
echo -e "FREQUENCY\tUSED\t\tWHEN NOT IDLE"
awk '
{printf (($1/1000)" MHz \t")}
{if ($2 == 0) printf ""; else printf ("%.1f %\t\t",($2*100)/"'"$tis1"'")}
{if ($2 == 0) print ""; else if ($2/"'"$tis2"'" > 1) print ""; else printf ("%.1f %\n",($2*100)/"'"$tis2"'")}
' /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state
echo ""

Output example:

Current frequency: 250 MHz

1200 MHz

Install nbench:

1. Install rootsh if you havent

2. Open terminal and write:

cd /home/user/MyDocs/Downloads/

3. Download by writing:

wget http://my.arava.co.il/~matan/770/n900/nbench
wget http://my.arava.co.il/~matan/770/n900/COM.DAT
wget http://my.arava.co.il/~matan/770/n900/NNET.DAT

(If you don't have wget: apt-get install wget)

4. write:

root

5. Make a directory:

mkdir /home/opt/nbench

6. Move the files to a better location:

mv /home/user/MyDocs/Downloads/nbench /home/opt/nbench
mv /home/user/MyDocs/Downloads/COM.DAT /home/opt/nbench
mv /home/user/MyDocs/Downloads/NNET.DAT /home/opt/nbench

(a tip is to use tab-key to finish easy.. like /h[tab] to make /home/)

7. To get permission:

chmod 777 /home/opt/nbench/nbench

8. Run and wait for it to finnish:

/home/opt/nbench/./nbench

or 
cd /home/opt/nbench/
./nbench
