The Advanced tab grants you fast access to an array of advanced features, among them the Memcached memory object caching system and the Varnish Cache web accelerator, which will help you optimize your sites and apps without needing to leave the Control Panel. Based on the web hosting package, these features are either included by default or are available in the form of easily gettable upgrades. InnoDB and NodeJS support is offered too.
Varnish Cache is a web application accelerator also called as an HTTP accelerator. You can install it in front of any web server that speaks the HTTP protocol and configure it to cache the content. Varnish Cache is really, really fast and will improve your site's loading speed. One of the main merits of Varnish Cache is the flexibility of its configuration language, VCL, which allows you to specify how incoming requests should be tackled.
Memcached is a generic distributed memory caching system for increasing the loading speed of dynamic database-driven 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 memory caching system uses a client/server architecture. The Memcached memory caching system is used by some of the most traffic-hungry websites on the Internet and is supported by popular web applications like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source DBMS. A database engine is the underlying software component that a database management system uses to create, read, modify and delete data from a database. Its latest release features considerable improvements in performance, stability and usability. InnoDB offers the standard ACID-compliant transaction features, along with declarative referential integrity support. It is included as standard in most binaries distributed by MySQL AB.
