SG Optimizer: One point caching solution from Siteground
In most of other recommended shared hosting solutions, when you set up Worpdress, you need to set up separate cache plugin to speed up your website.
There is only one issue with this set up. The backend server is managed by your hosting solution and caching plugin can work with WordPress files & limited settings only.
This leads to code of two different companies interacting with each other. Only in certain cases (like WPX Hosting) you get recommendation from hosting company about their preferred caching plugin. This is done because their server have code matching with that plugin.

Whereas, in case of hosting solution providing caching and speed solution, this issue is resolved.
In same provider setup, the backend of your server as well as caching solution works in collaboration with each other. This leads to faster performance for your website.
SG Optimiser is one such solution. And that too from non-premium WordPress hosting company.
Features of SG Optimiser
The SiteGround SuperCacher system provides several layers of caching for your site – Static Cache, Dynamic Cache and Memcached.
Static Cache is switched on by default for all our users and is not WordPress specific. The greatest performance boost for WordPress is achieved by using the Dynamic Cache and the Memcached.
Here is the list of all the features now covered by SG Optimiser.
- Image Compression
- Gzip enable
- https force
- Lazy Load images
- Query strings from static sources
- Browser Caching
- Dynamic Caching
You need to enable Memcache & Dynamic caching in you cPanel before enabling them in plugin dashboard.

Here are the screenshots of the plugin with all the required settings:
As you can see that there is nothing you need to think about. It is all install, switch on the options & that’s it.
How to enable Memcached & Dynamic cache in Siteground cPanel
For the cache to function properly, you need to enable dynamic cache and memcached option from cPanel of your hosting account.
To enable these options, click on SuperCacher on cPanel:
Once clicked, you will reach the SuperCacher config section, with three tabs, each for each level of caching.
- Level 2 (Dynamic cache): Dynamic caching is the second layer of site performance improvement. It creates copies of your website’s dynamic content and stores them in the server RAM. This level onwards require SG Optimizer to be installed on your site.
- Level 3 ( Memcached): The last level of optimisation from server side. The Memcached technology speeds up database calls, API calls and page rendering by storing data and objects in memory to reduce the number of times a database is queried.
Purge SG Cache setting
Optimizer plugin provides an automatic cache purge option.
As per Siteground, they have developed a set of rules to purge the dynamic cache in a smart, efficient way depending on the change that has occured on the site. It does a full purge on events like category deletion, plugin and theme update or switch, WordPress core update, etc.
And smart purge on smaller changes. It is advised to keep this setting as ‘on’
How to speed up your website further
There is only so much that your hosting and cache plugin can do for speeding up your site. It also depends a lot on your theme that you installed and other optimisations to speed up your website.
With mobile first indexing and other page loading factors being important ranking factors, it makes sense to focus on speed of your website, right from the beginning.
