I think we have many chances, Robert,

1) ANTLR developer promise that 3.0 will be much faster of 2.7

2) we SELF can yet profile ANTLR and try improve it.
    I have see major problems in their code.
    I have told them many times.
    but they just say:
        way want correctness.
        optimization is devil...

Few guys on their list have told they was able easy enough speed up ANTLR in
5-8-10 times doing some tricks.
