New issue 2581: heapq.merge is slow in pypy3 https://bitbucket.org/pypy/pypy/issues/2581/heapqmerge-is-slow-in-pypy3
Matteo Dell'Amico: heapq.merge runs definitely slower in pypy3 than in python3. This script: ``` #!python import heapq data = [range(10000) for _ in range(100)] list(heapq.merge(*data)) ``` runs on my machine on around 1.2s on pypy3 and 0.6s on python3. Antonio is a friend of mine and asked me to report this :) _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
