New issue 1818: xml sax/BytesIO performance regression since 2.2.1 https://bitbucket.org/pypy/pypy/issue/1818/xml-sax-bytesio-performance-regression
larstiq: On irc IvIePhisto mentioned a performance regression. To reproduce I downloaded https://raw.githubusercontent.com/IvIePhisto/ECoXiPy/master/tests/performance/xml_sax.py and ran from timeit import repeat print repeat("from xml_sax import create_testdoc; create_testdoc('title', 'content', 2**4, 'text')", number=100) There are some numbers to tweak; with these settings I got on my linux32 laptop: pypy 2.2.1 [1.6042330265045166, 0.6979169845581055, 0.8283989429473877] pypy 8a9c64ba35dc [27.671435832977295, 32.030592918395996, 36.68885684013367] _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
