I remember having spent considerable effort making the ANTLR Ada95 grammar and parser [1] comparable in speed to GNAT in -gnatc mode (syntax check only).
I reached that goal by eliminating the syn preds (syntactic predicates) from the grammar. That bought a speedup of approx. 20 times. However, this was ANTLR v2 , and I haven't checked again with later ANTLR versions.
