New issue 2733: pypy3 slowdown for json_dumps benchmark https://bitbucket.org/pypy/pypy/issues/2733/pypy3-slowdown-for-json_dumps-benchmark
mattip: Using the cpython performance set of benchmarks, pypy3-v5.10.1 is very slow as if the JIT is off. ``` #setup python -mpip install performance; python -mperformance venv create pypy2 -mpip install performance; pypy2 -mperformance venv create pypy3 -mpip install performance; pypy3 -mperformance venv create # runs the bnechmark python -mperformance run -b json_dumps venv venv/pypy3* python -mperformance run -b json_dumps venv venv/pypy2* python -mperformance run -b json_dumps venv venv/cpython* ``` Gives me ~5ms for pypy2, ~17 ms for cpython2, ~50 ms for pypy3 _______________________________________________ pypy-issue mailing list [email protected] https://mail.python.org/mailman/listinfo/pypy-issue
