If you have a TCL interpreter close to you, I suggest you to try your benchmarks again, you will see other curious results :-) (If you don't have TCL, or you don't want to learn how to use it, you can also try Python/Perl REs, but they are sometimes less efficient than TCL ones).

I don't know. There are several ways to speed up a RE engine, so maybe Java regex is more refined.
