There are a number of variables at play here though, one of which is who t=

peering points you'd have to cross. If the endpoints were already setup, =
I'd schedule a number of decently sized (big enough that it takes at least=
5 - 10 minutes for scaling to do its thing) test transfers hourly or once=
every couple hours over the course of a week to get a baseline and unders=
