Hmm. Can you try the development version of Org?
If you are just using a bare flyspell-mode, it generally gets slow on
large Org files. We have made a number of improvements in this area on
development branch.

Usually, you can just re-search for appropriate Elisp variable prefix.
Or, if you use customize interface, saving customization will dump all
the non-default settings into your init.el
Or you can bisect the config to hunt for less obvious issues using
