“wget” is a very handy Unix command line utility to download files over http. It not only shows details about the connection but also tracks current and overall download speed in KB/s or MB/s. Unfortunately, it’s not part of Mac OS X. If you already own Apple’s Xcode development environment you could easily compile your own wget binary or just download it from this site’s download area.

You could do something similar with curl (which is included in OS X by default) but I prefer wget’s output over curl’s.
