A correction, the Fedora Man page for cpuspeed says
"Many modern Linux systems support in-kernel cpu frequency
scaling. The cpuspeed daemon only works in conjunction with
the ’userspace’ frequency scaling governor. Other gover-
nors, such as ’ondemand’ and ’conservative’, rely on the
Linux kernel to adjust cpu frequencies on the fly without
the need of any user-space assistance, such as that pro-
vided by cpuspeed.
Red Hat and Fedora distributions employ a unified configu-
ration file for both scenarios, as well as a cpuspeed init
script that will configure either cpuspeed or in-kernel cpu
frequency scaling, as appropriate.
FILES
/etc/sysconfig/cpuspeed, configuration file
So simply set GOVERNOR=PERFORMANCE
You can also put in the min and max speeds
and
edit
/etc/init.d/cpuspeed in a appropriate way
That will solve all of the problems if it is due to scaling
