Remember, there are only so many resources to serve up the files. If you’re on a small server, that’s going to seriously slow things down. If 100 people all access your site at once, that means 5,000 file requests in one second. Let’s say that your website uses 50 file requests every time it loads up.
Your server can only handle a certain amount of requests per second. Every CSS file, every image, every social sharing button, and every piece of Javascript is a new file request. It’s how many of them there are.Įvery small element on your site requires a different file request to load. I’ve already explained how big, heavy elements take much longer to load. Or you might have an explainer text as part of a large image on your homepage.Īs you can imagine, graphics like these take a lot longer to load compared to a simple font alternative. You might be using an image to display your logo, for example. If the backend of your site is clogged up with excess coding and javascript, it’s going to take longer to drag it up.Ī lot of websites still use images to display text.

If you’re familiar with CSS, HTML, and Javascript, you’ll know that there is an enormous amount of code behind your website design.įor example, there are 60 million lines of code on Facebook alone. One of the densest elements of your site is the code that creates it. Large, dense elements will slow down your website. But, heavy formats like TIFF and BMP are going to eat huge chunks into your load time. Browsers can load JPG, PNG, and GIF images nice and quickly. If you’ve got a ton of large images on your website, you’re adding extra load time for every picture. Large, heavy items are going to take longer to bring out.Ī large image is going to take a long time to load up. When you think of it like this, it’s simple. This is like our shopkeeper bringing your stock out of the back.
The server will carry content, text, and images. Things have improved since broadband, but the general rule still applies.Īfter you ping the server, it will start carrying each bit of the website to your browser screen. Extra large images (and complex file format)ĭo you remember the old days of dial-up internet? A large image could take up to a minute to load, one small bit at a time! It was agonizing!
Your server will try to manage all the extra traffic, but it will slow down somewhere.Ĥ. But now the backend stuff is slowing down too. They have to call extra staff from the back to help serve everyone. Not only that, but the shop then needs to drag additional resources in to help. The more people come into the shop, the slower they get served. If you’re experiencing a lot of traffic, it will eventually cause your website to slow down.Īt its current level, your web server can only serve a certain number of people at once. Then, it has to travel all the way back across the ocean to load it on their screen. When a Japanese visitor clicks on your website, the information has to travel all the way across the Pacific ocean. Let’s say your server is based in America. When you click on a website, you send a message to the server. The data goes through cables, and it’s transmitted over satellites.Ī similar thing happens when you click on a website. That’s because the information has to physically travel to get there. If you’ve ever made a long-distance call, you know that it takes longer to make the connection. If your site is slow, it’s because you’re in a queue with lots of other sites! A cheap web host will usually give you a shared server, which means you’re sharing space and resources with countless other websites. Poor server performance is almost always down to your web host. No matter how quick everything else is, a slow server will always give you a slow start. If your server’s performance is poor, it will take longer to respond. It’s asking for all the information and data, so it can load up your website. The very first thing that happens is this: Your browser (Firefox, Safari, etc) sends a ping to your server. Your visitor is asking your engine to start up. When someone clicks on your site, it’s like turning the key in the engine of a car. Slow site kill sales!
