It's obvious, no? My patch causes the slowdown. On a timeit microbenchmark, I don't see such slowdown. That's also why I suspect that pybench is unstable. python3.6 -m timeit '{}' says 105 ns with and without the patch. python3.6 -m timeit 'd={}; d[1]=1; d[2]=2; d[3]=3; d[4]=4; d[5]=5; d[6]=6; d[7]=7; d[8]=8; d[9]=9; d[10]=10' says 838 ns with and without the patch. I have to "cheat": I run timeit enough times until I see the "minimum". ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26058> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
