In addition to YSlow and WebPageTest mentioned in other answers I use the LORI (life of request information) extension for Firefox during development to give a quick indication of page speed.

https://addons.mozilla.org/en-US/firefox/addon/1743/

It adds a few fields to the status bar to give you a quick overview of some important figures: time to first byte, time to completion, total size, number of requests

Google-Chrome and Opera have builtin tools to analyze websites, including loadtime.
