    Uneven CPU usage

    Ubuntu 12.04 has a slight lag/stutter and I notice that the CPU load is distributed very unevenly in the System Monitor. I have an Intel Core™ i7-2630QM 2 GHz in my Lenovo Ideapad Y560p. It's a quad core with hyperthreading so it shows as 8 CPUs. CPU 1 usualy has 80-100% load, and CPU's 2, 3, and 4 have about 20%, while CPU's 7 and 8 are usually 0-5%. I can't disable the Hyperthreading in the BIOS because it is a laptop. I watch alot of youtube videos, and it is frustrating watching the videos stutter and skip while a good portion of my CPU is being unused.

    Is there a way to assign CPU 7 and 8 to Firefox and help decode the flash or at least have Ubuntu evenly distribute the processing load evenly and increase system speed and response? I'm fairly new to Linux and did some google searches, but did not see anything related to this problem. *I just noticed that I accidentally posted this in the wrong section and I don't see a way to delete it and move it to the right section*
