Back-end is very slow. I just installed J3.0.1 core - no extensions, no templates, no anything extra - just a raw naked Joomla. ... And the back-end is annoyingly slow. Even, the front end is not fast J2.5 is much faster even with dozen of heavy 3rd-party components installed.
Is there anybody else, who is experiencing the same (or I have to look for the reason somewhere else)?
