I started using CEDET with Emacs and although it works fine sometimes it is too slow.
For example if I write
std:: and wait for suggestions then in the minibuffer says
parsing file.cpp (LL) done
and for 1-2 seconds it freezes and I can't write. Then if I repeat it although it doesn't say anything in the minibuffer it still freezes the same. Eventually it shows the list of possible items but after that "freeze time".
Why is that happening? How can I fix it? I don't thing that this is the default behaviour as it is very annoying.
