Opcode caching involves compiling PHP into pre-compiled bytecode, which eliminates the need for PHP to be re-interpreted for each request. It’s great for speeding up huge apps with a lot of include/require declarations. Page loading times can be reduced from several seconds to less than 500ms using OpCache. The “Select PHP version” option in cPanel can be used to enable OpCache. Then you simply click the OpCache icon to complete the process. However, OpCache should only be disabled when troubleshooting or developing a website.
WordPress and Caching
Plugins enable caching in WordPress, and installing them is rather straightforward. To do so, go to wp-admin, click the Plugins icon, then the Add New icon. The name of the plugin you want to install is then typed in. There are a variety of WP caching plugins available, each of which works differently based on the themes and other plugins you have installed. The following are the top three:
WP Super Cache, W3 Total Cache, and WP Fastest Cache are all caching plugins for WordPress.
To prevent causing conflict and actually slowing down your performance, only install one of these plugins.
Take advantage of browser caching
Browser caching allows a customer’s web browser to download CSS, JS, pictures, and other static assets into local storage for a predetermined period of time, lowering page requests and hence server load. By adding the following lines to your.htacess file, you can enable browser caching:
Compression with Gzip
The Gzip compression algorithm is used to minimize the size of data sent from your server. When initiating an HTTP request, all of the most popular browsers support Gzip compression and search for the particular header. The use of Gzip compression resulted in faster loading times and smoother performance.
The photographs you publish should be less than 500KB in size to avoid slow loading times and to improve your SEO. You can use WP Smush, one of the many WordPress plugins, to make sure your photos fulfill these requirements.
