I don't think it is clear that tracing JITs are better.
Tracing often implies some other characteristics and features, such as level of inlining, specialization and guards versus arbitrary control flow, but method JITs are not prevented from adapting these techniques.
The advantages and benefits are a lot subtler than tracing versus method JITs.
Indeed, I don't think anybody really knows the answer yet, under which circumstances which of the two methods is better. Somebody should try to do a controlled study . Cheers, Carl Friedrich
