@Canonical: Why don't you make the lowlatency kernel as the default one instead of generic kernel? This should solve the problem of bad responsiveness correlated with graphical user interface.
Even if the throughput isn't getting better with lowlatency kernel - it feels much faster if your mouse pointer moves _without_ dropouts or menus pop up instantly under heavy disk I/O.
On graphical desktops it's not always the real throughput what makes the system feels fast, but the responsivness! Even if it takes a second longer to copy a big file, your system "feels" much fast if mouse pointer still moves _without_ dropouts or menus pop up instantly.
