Bug Description
I have been using Xubuntu 13.04 with good performance.
Recently I have tested Xubuntu 13.10 and Xubuntu 14.04 LTS beta. I see noticeable performance regressions on these with display updates. Merely typing in the terminal has noticeable screen lag.
I have tested Lubuntu 14.04 beta and the display performance is markedly better than that in Xubuntu. The procedure I used to migrate was:
sudo apt-get install lubuntu-desktop
sudo apt-get purge xubuntu*
sudo apt-get purge xfce*
and a reboot.
This is not a performance bug in xubuntu-terminal. Display responsiveness with LXTerminal and other terminals and text editors is consistently slow under xubuntu-desktop on 14.04 (and 13.10) whereas the display is responsive under lubuntu-desktop. There is also no problem with display performance when typing in the console (Ctrl-Alt-F1) on Xubuntu 14.04.
I am using the x86_64 versions of Xubuntu 13.10 and 14.04 running as a guest under VirtualBox 4.3.10 on a Mac OS X 10.9.2 host. The VirtualBox guest additions are installed correctly. The effect of the 3d acceleration option in VirtualBox makes no difference, nor does the VirtualBox version (tested back to 4.2.22).

Thank you for taking the time to report this bug. Can you please turn off XFCE's built-in compositor (Settings Manager > Window Manager Tweaks > Compositor) and test if this change improves the overall performance?
