Do you by any chance have `backtrack=true;` in the options-section of your parser? If so, you could try to add `memoize=true;` to it: that might increase the parse-time (most probably will). However, it would be better to remove `backtrack=true;` and only add predicates to rules where needed. ... > > However, this double parsing creates a new instance of the CSS2.1 parser > for > each successfully parsed piece of the core grammar.
