Google Public DNS, openDNS co-locate with the main ("top") internet exchange points around the planet, to automatically shorten the routes between DNS's and networks available to them.
They use what's called Anycast routing, to make sure your connection "talks" to your nearest data centre. In theory, this
should mean web pages load faster,
maybe more reliably, and so on.
Given the complex nature of the internet, location of exchange points, etc, things may not always be "optimal".
However, other factors which
could slow down your connection include your actual modem (its settings and where it is physically), the presence of malware/virus on the main computer, the web browser you use...lots of things.
If large web pages with lots of content take forever to load, the "problem"
might be a browser issue, the site itself might be poorly constructed, your browser's web cache might have redundant entries
(flushing the cache sometimes can work wonders).
All things being equal, a clean modern computer with a decent modem/router, up-to-date operating system, good web browser,
should be able to deliver an acceptable internet experience.
In the case of
Telkom Speedy, issues can arise if the copper wiring to your phone has been damaged, the splitter between the phone line and computer is fucked,
you're on the border of the nearest connection point, a "technician" at the office has assigned you a faulty (or flaky) line, there are too many people in your immediate area trying to use the same junction box at the same time, etc.
And last, but not least, if you're using wireless sevices on your home network, somebody
might be piggy-backing on your connection (that's a security issue).
Third-party DNS providers like Google Public DNS or OpenDNS
may be faster for you.
Namebench will let you know if they are.
My latest speed tests (an hour ago) show the following:
Have "fun" tweaking your internet happiness.
Then there OpenNIC DNS servers (
Namebench will
probably pick these us during a scan).
My nearest OpenNIC DNS servers…
