New description:
The import of ''twisted.persisted.styles'' takes a significant amount of
time on sage startup:
{{{
$ time ./sage -startuptime|grep twisted.persisted.styles:
twisted.persisted.styles: 0.093 (sage.all)
real 0m1.422s
}}}
Most functionality from that module seems not to be used in sage. The
attached patch removes everything but the needed functionality:
{{{
$ time ./sage -startuptime|grep twisted.persisted.styles:
real 0m1.280s
}}}
