We can use the Google PageSpeed Insights tool (https://developers.google.com/speed/pagespeed/insights/) to evaluate the performance of IGWEB's home page.

Figure 1.10 is a screenshot that shows the result of evaluating the desktop edition of IGWEB. At the time of writing, IGWEB scores 97/100 for the desktop browsing experience, and 91/100 for the mobile browsing experience. According to the tool, the 90+ score attained for both the desktop and mobile editions indicates that the IGWEB home page applies most performance best practices and should deliver a good user experience.
