For the Cairo Charts demo, the margins between the six tested Linux desktops were less, but GNOME / Xfce / LXDE were still running faster than Unity and KDE in the SNA-enabled environment.

There wasn't much of a difference between UXA and SNA with the gradients test and surprising Unity and KDE ended up being faster than the four other open-source desktops.
