Ok, but what about Lubuntu 14.04 compared to Lubuntu 12.04?

Your comment is only comparing LXDE with other desktop managers, instead of comparing different versions of Lubuntu.

EDIT: It occurs to me you may have mistaken "LTS" for the desktop manager name (LXDE) when you replied. LTS means "Long Term Support".

Sorry late on the reply. I didn't mix it up. I was commenting that in my past recent experience, upgrading resulted in a slower system. I was just warning others not to do that. I'm not upgrading to 14.04 because I don't want a longer boot.
