The Advanced tab grants you swift 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 sites and apps without the need to move away from the hosting Control Panel. Depending on the hosting package, these features are either included by default or are available in the form of easy-to-get upgrades. InnoDB and NodeJS support is available as well.
Varnish Cache is a web application accelerator also known as an HTTP accelerator. You can install it in front of any web server that speaks HTTP and configure it to cache the content. Varnish Cache is really, really fast and will increase the speed of your site. One of the important advantages of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which enables you to define how incoming requests should be dealt with.
Memcached is a general-purpose memory caching system for increasing the loading speed of dynamic database-powered 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 memory caching system uses a client'server architecture. The Memcached system is employed by some of the most frequently visited sites on the Internet and is supported by famous Content Management Systems like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source relational database management system. A storage engine is the principal software component that a DBMS uses to create, read, update and delete data from a database. Its latest edition offers substantial improvements in performance, stability and usability. InnoDB offers the standard ACID-compliant database transaction features, along with declarative referential integrity support. It is included by default in most binaries distributed by MySQL AB.
