A slow website will leave users waiting and frustrated. To assure this doesn’t happen to your website, use Pingdom. It is a free, online tool which tests the performance of your website. The tool provides an overall performance grade, the number of requests, the load time, and the page size. It also compares the load time to all other websites tested. Pingdom lists out the requests it made and the time it took to complete each one. In addition, a break down of the performance grade into more specific common problems is provided, while also including an analytics page. Furthermore, Pingdom provides a DNS server test and a test for network connectivity to a server. These tests help identify domain errors to help keep your website running smoothly.
