I'm not that familiar with auto-complete, but if you check the Emacs Wiki:
you will find this text:
If you are using the current development version of AutoComplete (0.20
at the time of this edit) be aware that ac-source-semantic is now
included in the package. Furthermore, if you are using the semantic
source, make sure that you have required semantic-ia in your init
file. If you do not then it falls back to a method of gathering the
tags that appears to not check the semantic cache slowing the whole
thing up rather tremendously (especially with omnicompletion).

I installed the latest repository version of CEDET and disabled the
version that is bundled with Emacs 24.3. After skimming the manual and
reading Alex Ott's article "A Gentle Introduction to CEDET" I made
several additions to my .emacs file. Once I made all of the recommended
changes, I tried to edit a simple Java file. Code completion with
auto-complete is functional, but extremely slow, even after the trying
the same function from the same class twice (System.out.println). I
would also add that CEDET does not seem to pick up the methods of the
objects statically in the packages either. I am not sure if this is an
error or functionality that just needs to be added at a later date.
My second problem is that when I try to edit a C file, auto-complete (I
am using version 1.4 that comes in the package repository) does not
bring up any completions. I tried several configuration changes to my
,emacs file in an effort to get the auto-complete menu to work. It works
great in Emacs Lisp mode. Additionally, normal semantic completion works
fine once enabled. Can anyone give me a hand with either of these issues?
By the way, the link to "smart completion debugging" in the CEDETmanual
