I doubt that 0.0% CPU usage and 5.3% MEM usage are the cause for the bad performance. How did you sort when running top? After running top push x to highlight the column you are currently sorting by, then push Shift+M to sort by memory and after that Shift+P to sort by CPU usage. This at least should work with a default "classic" top. -- xubuntu-users mailing list xubuntu-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/xubuntu-users
