Advanced Features
The Advanced tab provides you with fast access to a set of advanced features, among them the Memcached distributed 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. Depending on the website hosting package, these features are either added by default or are available in the form of easy-to-get upgrades. InnoDB and NodeJS support is offered as well.
Varnish
Varnish Cache is a web accelerator also popular 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 really, really fast and will improve your web site's loading speed. One of the main attributes of Varnish Cache is the flexibility of its configuration language, VCL, which permits you to determine how incoming requests should be dealt with.
Memcached
Memcached is a general-purpose distributed memory object caching system for boosting the load speed of dynamic database-driven sites. 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 distributed memory object caching system uses a two-tier architecture. The Memcached memory object caching system is employed by some of the most traffic-hungry websites on the Internet and is supported by famous CMSs like Joomla and WordPress.
Node.js
Node.js is a software system for writing scalable Internet apps. Built on Chrome's JavaScript runtime, Node.js uses an event-based, non-blocking input/output model that makes it lightweight and effective, perfect for real-time data-rich apps. Node.js uses Google's V8 JavaScript engine, libUV, and a number of built-in libraries.
InnoDB
InnoDB is the default storage engine for the MySQL open-source database management system. A database engine is the primary software component that a DBMS uses to create, retrieve, modify and delete data from a database. Its latest release offers considerable improvements in performance, security and usability. InnoDB offers the standard ACID transaction properties, as well as referential integrity support. It is included as standard in most binary distributions from MySQL AB.
