Another online tool that web developers can use to measure site performance is the simple to use Stella. This utility, when provided a URL, measures the time it takes to fetch your DNS records, receive a response from the server and download the full page of content. Overall, this is a good indicator of how fast your site is.
One nice feature about Stella is that it remembers tests run against the same site recently so you can see if tweaks you may have made make a difference. Additionally, you can see how your site’s performance stacks up against other queries which have been run against the service.
While this tool doesn’t make any suggestions on ways to improve your site, the data is gives you can at least get you an idea of how fast (or slow) your site is.
