There's a good chance you need to invest in your wildignore or ctrlp ignore settings. I run: https://gist.github.com/67de417c5c38f0ff8093 in the end of my ~/.vimrc to ignore the SCM directory, the tmp directory and my data-dirs (you can adapt as required) - this makes ctrlp really responsive for me. YMMV.
