I saw you were testing 100MB files. Have you done any measurements with smaller input files?
Also, in your blog, you said "Perl consciously accepted a regex slowdown to route around a pathological case where search time could explode to infinity", which might be related to the bug that Mariano mentioned in his mail (which Sun gleefully claimed as not a bug). And, for evidence that things implemented in Java (on Android) have to be slow, let me present the one and only interpreter in the Dalvik VM :-) If I have time, I will actually do some benchmarks on Java regexp vs JavaScript regexp on the G1.
