Accelerating the website can often be a demanding job requiring detailed planning, knowledge of different areas, with a focus on testing and evaluation. Often, there are several teams working on this segment: web developers, system administrators, network experts, and other professionals. In this article, we will show you how to speed up a website on a CentOS 7 server.
Why is the website speed so important?
The answer is simple – the download speed affects the ranking of your website on search engines. The website’s download speed is included in the search engine ranking factors, and therefore this is an important SEO factor. Slow websites negatively affect the conversion rates that are crucial to the success of every online business.
Use fast and reliable hosting
It’s obvious that you need to use reliable web hosting if you want your website to be loaded fast.
Enable gzip compression
Compressed files are much smaller and are downloaded much faster, which in the end greatly reduces the time needed to load those content from the end user. The process of compression (on the server side) and decompression (on the client side) burdens the processor, but modern processors are fast and easy to cope with, while the speed of the Internet connection is still often a bottleneck. So compression contributes to the overall speed of the website, in the vast majority of cases.
In order to enable GZIP compression, it is necessary to configure the web server so that it compresses all files before sending it compressed in GZIP format. Specific configuration commands depend on the type of the server. On CentOS servers with Apache, the simplest solution is to modify the .htaccess file located in the root directory of your website.
If you do not have this file, you need to create it yourself and enter the following code into it:
Configure web browser caching
In order to allow caching of such files, it is necessary to re-edit the .htaccess file in the root directory of the website, i.e. add the following code to it:
By using these simple .htaccess rules for caching, you can dramatically improve the speed of the website.
Use a CDN
Content Delivery Network (CDN) is a collection of web servers distributed across multiple locations in order to provide more efficient content delivery to users. Using this solution can help your website get faster by 20% or more.
Reduce HTTP requests
In order to reduce page loading time, you also need to reduce HTTP requests. This means that you need to:
- reduce the number of CSS files or try combining many CSS files into one bigger file,
- reduce the number of images.
That’s it, your website should be faster now. If your website based on WordPress, you can use plugins to do some of the steps mentioned above.
