#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
