I hope not the former. Given that loopback performance is
*significantly* faster than network performance, increasing the
performance of the loopback driver in these somewhat artificial
ways (that differ from the real network device path) simply
*increases* the inaccuracy of their testing and the conclusions
they can draw from it ;).
