I actually disabled my cpuspeed even though I fixed it (the driver was bad; my box was making odd sounds and the daemon slowed my apps). This cpuspeed is a powermanagement tool; It makes the cpu run at different frequencies depending on workload, disabling it makes it work at maximum - ideal for laptops to save battery, but not for desktops. To disable, enter the Desktop - System Settings - Services, and uncheck cpuspeed. DO NOT STOP IT, or it will halt the cpu on the frequency its currently set to, and you will need to reboot.

However, if youre fine with the cpuspeed, dont worry about it.
