The benchmarks are delivered with PP2, so far there are pre-prepared benchmarks for:
- simple arithmetic expression grammar
- smalltalk grammar/smalltalk parser
- java parser (if you download PetitJava)
You can run it on your own, e.g.:
PP2Benchmark exampleSmalltalk
Currently I am working on optimization of context sensitive grammars as well.
As I said before, there is a space for optimizations. If you can identify a bottleneck, there is a very high probability the PP2 can be extended to fix that.
