I use TeX-fold extensively (I find it's the only way I can keep my LaTeX 
buffers looking sane...) and while it can take some time for a buffer to be 
folded, especially on a slow computer (right now I'm using an eight- or 
nine-year old netbook with 2GB of RAM and an Atom CPU), typing and editing text 
isn't any slower at all, in my experience.

In order to fold new text, though, you shouldn't refold the entire buffer. 
There's `tex-fold-paragraph', which I use for that purpose. I even bind it to 
`C-RET' to make it easier to type. (`C-c C-o C-p` is a bit cumbersome IMHO). I 
also advice the command `LaTeX-insert-item' so that typing `M-RET' to insert a 
new "\item" macro automatically folds the preceding "\item".
