New issue 2980: awful bisect performance in pypy3 compared to cpython or pypy2 https://bitbucket.org/pypy/pypy/issues/2980/awful-bisect-performance-in-pypy3-compared
AliReza Mosajjal: Hi. I created a simple code to search in IPs and filter out which one is from a certain country. Here's the code sample: https://pastebin.com/NA3jpLei to run it, I use this command (for testing): ``` shuf -i 16777216-4294967295 -n 1000000 | python main.py ``` Now take a look at the output with different python versions: ``` shuf -i 16777216-4294967295 -n 1000000 | time pypy3 main.py 11.13user 0.05system 0:11.93elapsed 93%CPU (0avgtext+0avgdata 94676maxresident)k ``` ``` shuf -i 16777216-4294967295 -n 1000000 | time pypy main.py 0.52user 0.06system 0:01.42elapsed 40%CPU (0avgtext+0avgdata 79356maxresident)k ``` ``` shuf -i 16777216-4294967295 -n 1000000 | time python2 main.py 1.09user 0.00system 0:01.94elapsed 56%CPU (0avgtext+0avgdata 9504maxresident)k ``` ``` shuf -i 16777216-4294967295 -n 1000000 | time python3 main.py 1.17user 0.01system 0:02.00elapsed 59%CPU (0avgtext+0avgdata 11380maxresident)k ``` What makes pypy3 slower (by a considerable magnitude) to other implementations? _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
