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?

[root@core ~]# cat /proc/cpuinfo

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.

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
