Linux Showing Low Processor Speed than windows

vijay_sastry · 03-21-2006, 11:02 AM

Dear Friends !

I am using both SuSE Linux & windows xp in my system.When i saw my processor speed in windows by right clicking my computer , it was 1.6 GHz. Now I used one linux command to see my processor information like this
$ cat /proc/cpuinfo

Alas ! Now my processor speed was just 1.1GHz. Why this decreased processor speed with linux?
How can I improve/increase it ?

My Current System Configuration :

Processor : AMD Athlon XP 1800+
MotherBoard : MSI
OS Installed : C:\windowsXP
NON-DOS: SUSE LINUX 9.2

Awaiting Your response , Thanking you all in anticipation

You probably have CPU Frequency scaling enabled.
try the command below while using your computer and see if it changes

Code:

watch grep \"cpu MHz\" /proc/cpuinfo

Build something or disable cpuspeed. FYI this is normal on laptop based systems, see;
