It depends on the system, the processor being emulated, and the nature of the code. The speed gains can be very high in the right situations.

Dead flag removal is definitely an optimization that's worthwhile for many older CISC processors with lots of flags (especially 68K.)

I don't know anything about using Java but you might want to turn to the dynarec mailing list if you want to discuss the subject.
