At SiteGround, we take website performance to heart. That’s why we have developed SuperCacher - our own powerful caching solution that accelerates website speed multiple times. It is available to all our clients and offers four caching options you can choose from.
The second level makes copies of your site's dynamic content and stores them in the server RAM.
The third level uses Memcached technology which 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. It’s a good option for sites that rely mainly on database queries.
The fourth option is HHVM which makes PHP-based websites super fast. It's only available on our Cloud hosting accounts.
All SiteGround shared hosting plans include all three levels of caching, except for the StartUp plan which comes with the first level of caching. You can manage your cache levels via our custom interface for SuperCacher in User Area → Manage Accounts → Go to cPanel → SuperCacher in Site Improvement tools. For detailed instructions about SuperCacher, please read our SuperCacher tutorial.
