New issue 2791: PyPy3: use W_IntObject instead of W_LongObject whenever possible https://bitbucket.org/pypy/pypy/issues/2791/pypy3-use-w_intobject-instead-of
Ronan Lamy: In pypy3, we have 2 implementations for app-level int objects: W_IntObject and W_LongObject. The former is similar to Python 2 ints and JITs nicely, the latter wraps `rpython.rlib.rbigint` and is much slower. Issue #2785 fixed one case where using W_LongObject instead of W_IntObject caused a major user-visible slowdown, but there are many more places where we create W_LongObject indiscriminately. It would probably make sense to always try to convert to W_IntObject. We should at least make `space.newlong == space.newlong_from_rarith_int == space.newint`. _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
