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 is noticeably laggy.
I have tested Lubuntu 14.04 beta and the 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. LXTerminal runs slowly under xubuntu-desktop on 14.04 (and 13.10) whereas xubuntu-terminal runs quickly under lubuntu-desktop.
I am using VirtualBox 4.3.10 on a Mac OS X 10.9.2 host and Xubuntu 14.04 x86_64 running as a guest, with the VirtualBox guest additions installed correctly. The effect of the 3d acceleration makes no difference, nor does the VirtualBox version; the same slowness occurs with Xubuntu >= 13.10 in older VirtualBox versions 4.2.x. |

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

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). |
