Server performance

To know what server performance affects your page load to time, let’s see what happens when someone goes to your URL. Well, when a user clicks on your website, his or her browser pings the server asking for all the information and data needed to load the website.

If the server isn’t performing up to mark, it will take more time to respond. Even when everything else functions smoothly, poor server performance will slow down the speed of a website. That’s why the server quality often come down to the website hosting service quality.

Cheaper web hosting services will come with a shared server. A shared server means multiple websites are sharing the same space and resources. Each site’s speed is slow because it’s in a queue with other ones. To improve the page speed, it’s good to consider having a better web host.

Server location

Website test - Server location can also impact your page load time

Therefore, picking a server that’s located relatively nearby your user base is a good way to speed up your page load. For example, in case most of your users are based in Africa, don’t host your website on servers based in anywhere else.

No caching techniques

Caching can considerably improve website performance. It is a very helpful technique by which the browser keeps frequently used data in its “cached memory”.

It means that next time when the users visit the website again, the browser doesn’t need to load the information and data all over again. The loading time will be reduced thanks to this faster data retrieval.

Without caching techniques, the websites have to load all the files and data every time when someone goes to the site. This is really unnecessary and will likely hamper the experience of the users when it can be solved with ease.

JavaScript issues

Using JavaScript/jQuery plugins makes it more convenient to add dynamic content to the web. But, if not implemented the right way, JavaScript can cause issues for your page load speed.

It takes time for JavaScript to be loaded, interpreted as well as executed. If you use multiple API calls in order to render JavaScript data, then it can lead to significant delays when loading the web pages.  

Website test - Too much flash content

Though Flash is useful for adding interactivity to a website, it can also contribute to the low page load speed. Flash content tends to have bigger file sizes, and more of it will, of course, slow down your web pages. 

If possible, you should consider reducing the size of your Flash files or even eliminating them so that your page loading speed will get improved. If you want to boost your web load speed, look for HTML5 alternatives to replace the existing Flash content.
