FreeBSD: How To fetch the ports from fast servers

Ports randomly gets it's source server list from bsd.sites.mk file located in /usr/ports/Mk/, as defined by the port maintainer. Most of the time downloading the source takes a long time if the remote server is not physically near to us.

In this case, we can tune the ports so that it fetches the sources from the nearest server. A nearer server normally means less latency and a faster connection.

The port fastest_sites will test the latency of the servers listed in /usr/ports/Mk/bsd.sites.mk. The file is suitable to be included in /etc/make.conf which tell ports where to fetch the sources from.
