Hi Saud copy.copy is a lot slower in new pypy. Minimal example to reproduce it:
import copy, sys class A(object): def __init__(self, a, b, c): self.a = a self.b = b self.c = c self.d = a self.e = b a = [A(1, 2, 3), A(4, 5, 6), A(6, 7, 8)] def f(): for i in range(int(sys.argv[1])): copy.copy(a[i % 3]) f() (run it with 1 000 000) The quick workaround for you is to write a copy function manually, since you use it in one specific place, that should make things a lot faster. In the meantime we'll look into the fix On Sat, Oct 29, 2016 at 8:02 AM, Saud Alwasly <saudalwa...@gmail.com> wrote: > here is the new zip file including the missing package > > > On Fri, Oct 28, 2016 at 10:58 AM Maciej Fijalkowski <fij...@gmail.com> > wrote: >> >> (vmprof)[brick:~/Downloads/dir] $ python Simulate.py >> >> Traceback (most recent call last): >> >> File "Simulate.py", line 9, in <module> >> >> from pypyplotPKG.Ploter import Graph, plot2, hist, bar, bar2 >> >> File "/Users/dev/Downloads/dir/pypyplotPKG/Ploter.py", line 1, in >> <module> >> >> import pypyplotPKG.pypyplot as plt >> >> File "/Users/dev/Downloads/dir/pypyplotPKG/pypyplot.py", line 3, in >> <module> >> >> from shareddataPKG import SharedData as SharedData >> >> ImportError: No module named shareddataPKG >> >> On Fri, Oct 28, 2016 at 12:42 AM, Saud Alwasly <saudalwa...@gmail.com> >> wrote: >> > Sure, here it is. >> > you can run Simulation.py >> > >> > On Wed, Oct 26, 2016 at 9:08 AM Armin Rigo <armin.r...@gmail.com> wrote: >> >> >> >> Hi Saud, >> >> >> >> On 26 October 2016 at 11:19, Saud Alwasly <saudalwa...@gmail.com> >> >> wrote: >> >> > I have noticed severe performance degradation after upgrading pypy >> >> > from >> >> > pypy4.0.1 to pypy5.4.1. >> >> > >> >> > I attached the call graph for the same script running on both: >> >> > it seems that the copy module is an issue in the new version. >> >> >> >> Please give us an example of runnable code that shows the problem.
