11740,reading integers from a file takes quadratic time,zimmerma,AlexGhitza,"[This problem was mentioned to me by Thorsten Kleinjung.]

Consider a file {{{b.sage}}} containing a single line {{{sigma = 111...111}}} with 200000 ones, and another file {{{c.sage}}} with
400000 ones. Then with Sage 4.7:
{{{
sage: t=cputime()
sage: load b.sage
sage: cputime(t)
1.7999999999999998
sage: t=cputime()
sage: load c.sage
sage: cputime(t)
6.7800000000000011
}}}

Magma V2.17-7 reads the 400000-digit integer in about 80ms, i.e.,
about 85 times faster than Sage. I consider this as a defect.",defect,new,major,sage-5.10,basic arithmetic,,,leif,,N/A,,,,,
