New submission from Antoine Pitrou <pit...@free.fr>: This patch speeds up _PyUnicode_CONVERT_BYTES by unrolling its loop.
Example micro-benchmark: ./python -m timeit -s "a='x'*10000;b='\u0102'*1000;c='\U00100000'" "a+b+c" -> before: 100000 loops, best of 3: 14.9 usec per loop -> after: 100000 loops, best of 3: 9.19 usec per loop ---------- components: Interpreter Core files: unroll_convert_bytes.patch keywords: patch messages: 145192 nosy: pitrou priority: normal severity: normal stage: patch review status: open title: speed-up conversion between unicode widths type: performance versions: Python 3.3 Added file: http://bugs.python.org/file23351/unroll_convert_bytes.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13136> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
