Hi Saud,

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. We (or at least I) can't do anything with a call graph.

A bientôt,

Armin.

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 <saudalwasli@gmail.com> wrote:
