Here is a patch which gets rid of small performance regression introduced by issue20426 patch. No need to check flags before cache lookup because patterns with the DEBUG flag are newer cached. $ ./python -m timeit -s "import re" -- "re.match('', '')" Before patch: 9.08 usec per loop After patch: 8 usec per loop |
