Why The Internet is Often to Blame for Performance Issues


But don't worry, there's something you can do about it.



A lot happens in the seconds between the click of a link in a web browser, and the opening of a new page on your computer screen. While it seems like a simple process from the user perspective, there's actually a complex system under the hood making this "automatic" action a reality.

What's important is that the process happens as quickly as possible—almost instantaneously in a perfect world. But for a site to perform well, everything has to go right from that initial click. If not, site visitors (and their wallets) go elsewhere. In fact, if users notice a lag of as little as one tenth of a second, many will abandon your site in the blink of an eye (roughly 400 milliseconds).

A site can be slow for many reasons, and most consumers—and companies, for that matter—don't know just how much can go wrong, much less where the challenges occur or why these issues cause Web delays.

A common culprit is poorly designed web applications not built for speed or functionality. More often, though, the biggest factor in web performance isn't what happens on the web server; it's what happens in the network.

Many issues can slow traffic from web server to browser and have a negative impact on user experience. Before any content crosses a network, a browser has to resolve a site's name to an IP address using the Domain Name System (DNS). There's nothing for a user to see during DNS resolution, so the faster a site's name resolves, the sooner the browser can connect to the server, start loading the page and give some feedback. Also, the speed of light in fiber-optic cable is only so fast. That means the distance between the site's servers and the site's typical users affects the site's performance. This physical distance is a hard limit on a site's maximum performance.
