Siteground is a top web hosting company and famous among the WordPress user because of its SG Optimizer Plugin. Generally, WordPress site owners use the W3TC Plugin, WP Super Cache or WP Rocket to speed up the site. I personally bought the Siteground hosting because of its Supercacher function and most of the people provided the positive reviews for the Siteground hosting on various forums and blogs.
It works same as other cache plugin but it gets full support from the server side, therefore, lightning speed of the site. Moreover, the main function of the plugin to serve the cache pages directly to the visitor, and optimize the server resource efficiently.
In this article we will provide you a step-by-step guide to install the Supercache plugin on your WP site and how to configure the setting in Siteground Cpanel and WordPress dashboard.
First, Install the SG Optimizer WordPress Plugin and active the plugin;
Go to Siteground Cpanel and find the SG Super Cache under Advanced option (Ref Picture below)
Level 1: Static Cache
The Static Cache option caches all the static content of your site such as images, JS Files, CSS Files and Flash images. Once this function is on, a request of visitor will be answered using the cached pages and it will not execute directly from the server, therefore, better performance of the site. Moreover, the flush button can be used to flush all the cached content, if you wish to make changes in site and want to see them immediately.
Level 2: Dynamic Cache
I personally like the second level of caching, it improves your site performance. Actually, this function creates a cache for dynamic content of your site and store it in the server RAM. It helps your site to load fast as it reduces the execution time and improves your server performance.
In simple words, dynamic caches will store entire pages in the RAM. And whoever will visit your site, the page will be served the content from the server’s memory. And it will reduce the time to collect the data every time from the database.
To enable the Dynamic cache option in Siteground Cpanel, download the application on WordPress and install it (If you have not already installed before). And slide the bar towards ‘ON’ button.
Level 3: Memcached option
If you facing an issue with site speed because of heavy database or improper database allocation. The Memcached will improve your site speed exceptionally. Once you will enable the memory cache option in Cpanel then you will receive the information regarding IP address and port number. An IP and port number are required to submit in the WordPress plugin. (Not required in many cases)
Level 4: HHVM
This function is not available for the shared hosting customer.
If you are hosting on dedicated or cloud server then this booster function is available in the SuperCacher tool. Simply enable HHVM function and it will show you a line which needs to be added in the .htaccess file of the site.
You can add this line anywhere and this script will use HHVM to compile PHP files.
Google Page Speed Option
Currently, this plugin does not support Google Page Speed. If you will activate the Google Pagespeed, the system will deactivate the Dynamic and static cache option. Therefore do not activate the option as currently, it is not compatible.
Siteground SG Optimizer Plugin Setting
After installation of the SG Optimizer WP plugin, activate all the available option. In most of the cases, these features will be activated (See Screenshot)
Also, make sure you remove all other WP cache plugins on site to avoid conflict. I am sure Siteground SG Optimizer Plugin will boost up the site performance and speed, this will help to rank better in Google Seach as Speed playing a vital role in ranking. Also, I would suggest comparing the site speed performance using the Google page speed tool. There you will see a significant change, I speed up my site by 120% overall and received grade 82 for Mobile and 89 for a desktop website. (I am talking about another website, not this)
