The Advanced tab gives you swift access to a set of advanced tools, among them the Memcached memory caching system and the Varnish Cache web accelerator, which will help you optimize your websites and applications without the need to leave the hosting Control Panel. Based on the web hosting package, these features are either included by default or are available in the form of easy-to-get upgrades. InnoDB and NodeJS support is available too.
Varnish Cache is a web accelerator also referred to as an HTTP accelerator. You can install it in front of any server that speaks HTTP and configure it to cache the content. Varnish Cache is very, very fast and will improve your website's speed. One of the chief advantages of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which enables you to define how incoming requests should be tackled.
Memcached is a general-purpose memory caching system for boosting the loading speed of dynamic database-powered web sites. It is used to lower the number of times an external data source (such as a database or API) is read by caching data and objects in RAM. The Memcached memory object caching system uses a two-tier architecture. The Memcached memory caching system is employed by some of the most regularly visited websites on the web and is supported by famous web apps like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source relational database management system. A storage engine is the main software component that a DBMS uses to create, read, modify and delete data from a database. The latest version of InnoDB offers serious improvements in performance, reliability and usability. InnoDB provides the standard ACID-compliant transaction features, as well as foreign key support. InnoDB is included by default in most binary distributions from MySQL AB.
