You're probably using a notebook. Your CPU is running slower to save
power since you're probably not doing anything CPU-intensive.

Open a terminal and do 'cat /dev/urandom > /dev/null' and then look at
your CPU speed. You should find that it will climb to 1400 MHz.

HTH.

Do you have cpufreq active?

Your CPU is speedstep capable. Most modern distros include a daemon
for adjusting CPU speed based upon load.

It's probably a notebook that you started unplugged from the mains power.
Mine is stupid enough to believe that I *want* to save power if I plug
the mains *after* powering it up ! And there's no way to force it to
switch from 600 to nominal freq afterwards ! So I have to connect it to
the mains first.

Willy

Caro, do a "$ grep -i cpufreq /boot/config".

what daemon? suppose in debian or redhat.

Isn't there a daemon to do that?

'cpuspeed' in Fedora/RHEL. Debian probably offers a dozen different
ones most of which I've never heard of :)

If you say this based on 'cat /proc/cpuinfo' output: isn't it true that
/proc/cpuinfo is static, and doesn't necessarily reflect the actual
speed of the processor?

no that's not true.

Hallo!

You could try:

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

It's possible that you have chosen "power_save".
You can see possible settings in

sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors

Try "performance"!
Then you should get your 1,4 GHz.
But be aware, that this is not powersaving!
Maybe you can play around with it.
A good possibility is to install an userspace application for governing
the cpu-speed lik cpufreqd
