Advanced Features
The Advanced tab provides you with fast access to an array of advanced features, among them the Memcached memory caching system and the Varnish Cache web application accelerator, which will help you optimize your websites and applications without needing to move away from the Control Panel. Based on the web hosting package, these tools are either included by default or are offered in the form of easy-to-get upgrades. InnoDB and NodeJS support is available too.
Varnish
Varnish Cache is a web accelerator also popular 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 contents. Varnish Cache is very, very fast and will improve the loading speed of your website. One of the major attributes of Varnish Cache is the flexibility of its configuration language, VCL, which allows you to choose how incoming requests should be dealt with.
Memcached
Memcached is a general-purpose memory caching system for boosting the speed of dynamic database-driven web 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 system uses a client'server architecture. The Memcached distributed memory object caching system is employed by some of the most popular web sites on the World Wide Web and is supported by famous Content Management Systems like Joomla and WordPress.
Node.js
Node.js is a platform for building scalable network applications. Built on Chrome's JavaScript runtime, Node.js uses an event-driven, asynchronous I/O model that makes it lightweight and efficient, suitable for high-performance data-intensive network applications. Node.js uses Google's V8 JavaScript engine, libUV, and a number of in-built libraries.
InnoDB
InnoDB is the default storage engine for the MySQL open-source DBMS. A storage engine is the principal software component that a DBMS uses to create, read, modify and delete data from a database. The latest release of InnoDB offers considerable improvements in performance, reliability and functionality. InnoDB offers the standard ACID-compliant database transaction properties, as well as declarative referential integrity support. InnoDB is included by default in most binaries distributed by MySQL AB.
