I grew interested in how fast my site loaded. Here are some tools I found to measure and analyze load times.
Web Page Speed Test – Provides recommendations to improve site loading time.
OctaGate Site Timer – Pingdom’s tool was inspired by this
Webslug – Compare the load time of two pages.
Webwait – Simple speed test
LinkVendor – Speed test with some data about external files.
To get even more detailed information you can install Firebug, a Firefox extension that’s extremely helpful for web development, but also has load time information. YSlow from Yahoo is an add-on that requires Firebug, but gives you a letter grade for the load time of a site. It also has suggestions on how to improve page load times.
