1) Propositions:

To test download speed, use a download manager and monitor speed while downloading something big from a powerful server, like Microsoft.
To test upload speed, download a high leech torrent, wait until it finished and monitor your upload speed in torrent client.
To test latency, use a ping (from CMD in Windows), and monitor time values. Example: ping google.com -t

Note somewhere your average download/upload speeds, also your latency. They will serve as reference values to compare speed test providers results.

To test my download speeds only, I'd generally grab a large file (on a wired network connection at home) from HEANet like an Ubuntu CD image.

ISPs have been known to treat certain classes of traffic differently, and in the past this has included not applying usual peak-time throttling to the better-known speed test sites. Transparent HTTP proxying was another common trick, although it is harder to do these days with increased use of SSL.

Probably the most reliable tests I have done recently was when I was over in the UK and needed to remotely pull data off my PC back in Dublin. That was an SSH tunnel over a non-standard port, so at least I knew it was not being monkeyed with.
