Speed of download

I need to find speed of download (for some common tcp protocols like
http) from a particular location.
Location is connected to its ISP by a T1 link. The link is shared by
over 80 users though not all are using the link simultaneously.

I need some pointers in devising a test strategy for finding speed of
download for that site, viz from a user's workstation.

One common way is finding speed of download for http downloads.
However the requirement is to come up with speed of download
independently rather than from the download speed calculated by File
download dialog box that is provided by OS.

Any utils, tools. Any pointers in writing a quick script/program etc

Why? That dialog box uses the same clock as you would use.

time wget ftp://name.of.site/name/of/file
should do it.

Buck,

We use rrdtool to track this sort of thing longterm. If you're using
Linux you could use iptables to count this.

If you have X windows, gkrellm is great for this sort of thing. The
"performance monitor" in Windows would also work.

You could also try command line http clients like wget or "siege" (a
stress tester).
