Not sure if this needs to be applied against firefox or xserver.Please
change if needed.
After I did a sleep(suspend to ram) My applications kmail,firefox-3.5,
ktorrent and xorg was consuming high cpu usage with xorg and firefox
leading the pack. After around 15 mins. It stabilised and cpu usage of
all processes returned to normal , like before I did sleep.
But even after that when ever I use firefox-3.5 (like normal browsing)
there is a spike in cpu usage.
top output during the time.
