Serhiy Storchaka added the comment: I posted benchmarks two years ago, in msg165795. Here are updated results:
$ ./python -m timeit -s "import io; n=100; d=[b'a'*n,b'bb'*n,b'ccc'*n]*10000" "s=io.BytesIO(); w=s.write" "for x in d: w(x)" "s.getvalue()" Before patch: 10 loops, best of 3: 42.3 msec per loop After patch: 10 loops, best of 3: 27.6 msec per loop $ ./python -m timeit -s "import io; n=1000; d=[b'a'*n,b'bb'*n,b'ccc'*n]*1000" "s=io.BytesIO(); w=s.write" "for x in d: w(x)" "s.getvalue()" Before patch: 10 loops, best of 3: 28.7 msec per loop After patch: 100 loops, best of 3: 14.8 msec per loop They don't depend from the resizing factor on Linux. I increased it in hope it will help on Windows. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15381> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
