Comment:
Hi Simon,
I haven't been following all the details of this, but thanks for the
patch! One question I have is whether there is a performance penalty for
this, and if so, to what degree is that acceptable. On my machine, I
noticed about a 10% slow-down for
{{{
sage: R.<x> = QQ['x']
sage: timeit('f = x^2 + 1')
}}}
after applying the patches at #9944 and here. I did not do any rigorous
testing so this may be spurious, but I'm not sure this should be given a
positive review unless this issue has at least been considered.
If this has already happened and I missed the discussion, then I
apologize. Just point me to it and I'll shut up and go away. :)
