After setting everything up and configuring GrandCDN with your website, you will, of course, want to check the results. This article provides a few tips on how you can check if GrandCDN is working correctly and test how your website performance improved around the world.
Check your website network waterfall and source code
After setting up GrandCDN, you will, of course, want to check if your website is configured correctly at all, especially if using a third party plugin or such as WordPress. This is pretty straightforward. The first thing you will need to do is open your website in your web browser and press Ctrl + Shift + I on your keyboard. This will open up the developer tools.
Now you will want to click on the Network Tab (1) and then Img (2) and refresh your website.
If everything went right, you will start seeing a list of requests to image files on your website as illustrated in the image above. By hovering over a specific request, you will get the URL of the image. To check if the images were served from GrandCDN, pay attention to the hostname they were served from as illustrated by point (3). If the images were served from the hostname you have configured in your GrandCDN account, such as grandcdn.grandcdn.net, this means that the website is successfully integrated with GrandCDN and serving data from it.
Check your GrandCDN statistics page and cache hit rate
Another simple way to test if GrandCDN is serving your data is to open the statistics page in your GrandCDN dashboard. If you see traffic and requests there, it's a good sign that GrandCDN is delivering traffic for your website.
Another important thing to note here is the cache hit rate at the bottom of the statistics page. When you have just added your website, this can be low, but if your website has a good amount of traffic and still has low cache hit rate, for example below 50%, it's a strong sign that there's something wrong and we would strongly suggest having a look at our cache hit rate troubleshooting article.
Check your website with one of the performance testing tools
After verifying that everything is installed correctly, you can have some fun seeing how fast your website is performing and to further improve your performance. We've created a list of three easy to use performance testing tools that you can use. When you've just created a new zone, always make sure to run the tests at least a few times, so that GrandCDN can successfully cache your website. If you're seeing any kind of errors, slow performance, you can have a look at our list of troubleshooting articles. They will help you find and correct any kind of problems with your website and GrandCDN integration.
