The Advanced tab provides you with fast access to a set of advanced tools, among them the Memcached memory object caching system and the Varnish Cache web accelerator, which will help you optimize your websites and apps without having to leave the hosting Control Panel. Based on the hosting package, these features are either included by default or are available in the form of easily gettable upgrades. InnoDB and NodeJS support is available as well.
Varnish Cache is a web application accelerator also known as a caching HTTP reverse proxy. You can install it in front of any server that speaks HTTP and configure it to cache the contents. Varnish Cache is really, really fast and will increase your site's speed. One of the main pluses of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which permits you to determine how incoming requests should be dealt with.
Memcached is a generic memory caching system for boosting the loading speed of dynamic database-powered websites. It is used to reduce 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 system uses a client'server architecture. The Memcached memory object caching system is employed by some of the most regularly visited websites on the World Wide Web and is supported by popular web applications like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source DBMS. A storage engine is the principal software component that a database management system uses to create, read, update and delete data from a database. The latest version of InnoDB offers considerable improvements in performance, security and functionality. InnoDB offers the standard ACID-compliant transaction properties, as well as declarative referential integrity support. InnoDB is included as standard in most binaries distributed by MySQL AB.
