New submission from Philip Jenvey: #9396 replaced a few caches in the stdlib w/ lru_cache, this made the mako_v2 benchmark on Python 3 almost 3x slower than 2.7
The benchmark results are good now that Mako was changed to cache the re itself, but the problem still stands that lru_cache seems to hurt the perf of inline res compared to 2.7. The fix for Mako did not affect the 2.7 benchmark numbers See more info here: http://mail.python.org/pipermail/python-dev/2012-November/122521.html ---------- components: Library (Lib) messages: 174550 nosy: brett.cannon, ncoghlan, pjenvey, rhettinger, zzzeek priority: normal severity: normal status: open title: re._compiled_typed's lru_cache causes significant degradation of the mako_v2 bench type: performance versions: Python 3.2, Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16389> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
