Also, if you are interested, you can compile a binary version:

$ dart compile exe optimized.dart

Thanks for the contribution! Unfortunately the simple.dart version takes a very long time (I think I waited to 60s and it still wasn't done, save I gave up). Is there something wrong with it, such as unbuffered stdin? I tried it on the file 1/10th the size (plain kjvbible.txt) and it takes ~9 seconds on that one. Any ideas?

I tried several times to rewrite this simple version, but my attempts were unsuccessful. ~37s on my i7-3610qm is minimum for all code variations, including "readByteSync". Can go deeper into this question, but this will no longer be the simple version 😄

Yeah, I don't think we can include it until we figure out and address that huge time for simple.dart, as currently it just makes Dart look really really slow. :-) Going to leave open for a while to see if others have suggestions.

Going to close this now due to lack of action.
