New submission from Carl Friedrich Bolz <[email protected]>: serge_sans_paill on IRC said the following:
I have been running pypy on the benchmarks from this repo: https://github.com/serge-sans-paille/pythran/tree/master/pythran/tests/euler and found a few situations where pypy performs slower than cpython for the following test cases, pypy is slower than cpython on my machine ('euler05', 27.2) 13 ('euler06', 17.4) 6.89 ('euler13', 12.1) 4.1 ('euler15', 20.9) 5.22 ('euler19', 409) 378 ('euler20', 142) 85.5 ('euler24', 48.8) 14.8 ('euler29', 14600.0) 13900.0 ('euler40', 24.3) 13.3 ('euler57', 13000) 2790.0 first enrty is the test case name, second entry is pypy's timing measuer by timeit, last entry is cpython timing I ran timeit -n 10 -r 3 ---------- messages: 5949 nosy: cfbolz, pypy-issue priority: performance bug status: unread title: Speed regressions vs. CPython for project euler programs ________________________________________ PyPy bug tracker <[email protected]> <https://bugs.pypy.org/issue1547> ________________________________________ _______________________________________________ pypy-issue mailing list [email protected] http://mail.python.org/mailman/listinfo/pypy-issue
