[antlr-interest] Debugger performance indicative of actual performance?

[Steve Bennett]

Using the debugger to parse some typical input is taking what seems
like a very long time to me - 5-10 seconds for a 7kb file. How
indicative is this likely to be of the performance I'll get in a
production environment? How much can a grammar be tuned for
performance?

I ask because 5-10 seconds could well be 2 or even 3 orders of
magnitude too slow...
