A tool that monitors the performance of a website and its server is presented in the form of a Chrome extension. It is designed to help you identify problems in the network connection of your computer, and the extension can also be used to see how fast a server responds to your requests. The tool allows you to monitor up to three websites at the same time.

The main window of the tool displays a list of URLs with their corresponding response times. You can select a website from the list to view its response time. You can also use the tool to view the latest response times for the websites you monitor.

The extension can be used to see the response times for the websites you monitor in the following ways:

The most basic way is to select a website from the list and then click on the "Start" button. This will start monitoring the website. You can then view the chart that is generated.

Another way is to select the "View" button.
