The travel faster than the speed of light. Thats a theoretical maximum in reality it will take longer than that for data to transfer. For instance it takes light about ms for a round trip between Paris and New York. If it takes twice that time for data to actually cross the Atlantic then the minimum time it will take to get a response from a server is ms. This is why CDNs are commonly used. CDNs put servers physically closer to users which is the only way to reduce the time it takes to reach the server.
How much does this matter Check out this chart from Chromes DevTools Kazakhstan Phone Number The life of a request measured by Chrome Dev Tools. All of the values in the red box are what Im considering latency. They total about ms. The actual transfer of content took .ms. No compression or reduction of filesize could help this the only way to reduce the time taken by the request is to reduce latency. Dont we need to make a lot of requests to load a page Itll take more than one request to load all of the content necessary to render a page. If that URL corresponded to a webpage the browser will usually discover that it needs to load more resources to render the page. These could be CSS JavaScript or font files.
It must recursively go through the same steps listed above to load each of these files. Fortunately once a server has been found DNS Lookup in the image above the browser wont need to look it up again. It will still have to connect and well have to wait for a response. A skeptical read of PageSpeed Insights tests All of the PageSpeed Insights evaluations cover things that can impact site speed. so easy to implement. And depending on how your site is designed some may be more impactful than others. Thats not to say.
