I'm not sure it is relevant here, but rewriting some of the simplest
and most commonly used functions in C may be an option.  Customize
first became usable fast when Hrvoje reimplemented widget-get in C.  

Basically, calling build-in functions is way faster than calling Emacs
Lisp functions.

I'm pretty sure RMS would accept including a C implementation of
gnus-member-of-range if it gave a significant performance boost.

Of course, you need to be sure the interface is not going to change
more, before doing that.
