So, after discussing with a Professor of our Department with a very good knowledge on the issue, he basically was in the line of "...JIT design decisions that a tracing JIT encourages versus the default design of a method JIT...", but to be more specific on the advantages he claimed that: "tracing JITs can discover optimization opportunities in common dynamic execution paths that are not apparent to a static compiler or a method-based JIT compiler". I think this is a nice comment overall, that the PyPy publications and the features they describe can back up nicely.

Also, I believe that Firefox, Chrome and Safari JavaScript JITs now are all method-based.
This needs to be confirmed but, I really think Firefox's TraceMonkey is a tracing JIT and Chrome's v8 is a method JIT. _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
Tracemonkey *was* a tracing JIT, at this point it's being (if not has already been) removed in favor of IonMonkey which is a method JIT.
Yes, it's removed from SpiderMonkey:
