If decimal depends on allocator performances, you should maybe try to implement a freelist. > Also I did set mpd_callocfunc to PyMem_Calloc(). I don't understand. 2% slowdown is when you use calloc? Do you have the same speed if you don't use calloc? According to my benchmarks, calloc is slower if some bytes are modified later. > The bytes() speedup is very nice. Allocations that took one second > are practically instant now. Is it really useful? Who need bytes(10**8) object? Faster creation of bytearray(int) may be useful in real applications. I really like bytearray and memoryview to avoid memory copies. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21233> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
