"re2c" can match strings much faster than perl code, by constructing a DFA to match many simple strings in parallel, and compiling that to native object code. Not all SpamAssassin rules are amenable to this conversion, however.

This requires "re2c" version 0.10.x (see "), and the C compiler used to build Perl XS modules, be installed.

Note that running this, and creating a compiled ruleset, will have no effect on SpamAssassin scanning speeds unless you also edit your "v320.pre" file and ensure this line is uncommented:
