F11/X86_64.
Thunderbird, Firefox, everything is being slowed down.
  Running ps aux give me this ,

/usr/bin/plasma-desktop

These are the two that seem to be taking up a lot of time.
Any Ideals ?

The properties on the /var/run/xauth/A:0-rJsTly file says it's unkown, 
it appears to be a binary file from the icon.
