The Advanced tab grants you quick access to a set of advanced features, among them the Memcached memory object caching system and the Varnish Cache web application accelerator, which will help you optimize your websites and applications without having to log out of the web hosting Control Panel. Depending on the hosting package, these features are either added by default or are offered in the form of easily gettable upgrades. InnoDB and NodeJS support is offered too.
Varnish Cache is a web 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 content. Varnish Cache is really, really fast and will increase your web site's speed. One of the key attributes of Varnish Cache is the flexibility of its domain-specific language, VCL, which enables you to determine how incoming requests should be handled.
Memcached is a generic memory object caching system for boosting the speed of dynamic database-powered sites. It is used to lower the number of times an external data source (such as a DB or API) is read by caching data and objects in RAM. The Memcached memory caching system uses a client/server architecture. The Memcached memory caching system is employed by some of the most traffic-hungry websites on the World Wide Web and is supported by famous web apps like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source database management system. A database engine is the primary software component that a DBMS uses to create, read, update and delete data from a database. Its latest release features significant improvements in efficiency, security and usability. InnoDB offers the standard ACID transaction properties, as well as referential integrity support. InnoDB is included by default in most binary distributions from MySQL AB.
