The Advanced tab gives you fast access to a set of advanced tools, among them the Memcached memory caching system and the Varnish Cache web application accelerator, which will help you optimize your web sites and applications without needing to log out of the hosting Control Panel. Depending on the web hosting plan, 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 web server that speaks HTTP and configure it to cache the content. Varnish Cache is very, very fast and will improve your web site's speed. One of the essential advantages of Varnish Cache is the flexibility of its configuration language, VCL, which permits you to determine how incoming requests should be dealt with.
Memcached is a generic distributed memory object caching system for boosting the speed of dynamic database-powered web 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 distributed memory object caching system is employed by some of the most traffic-intensive websites on the Internet and is supported by popular CMSs like Joomla and WordPress.
InnoDB is the default database 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 edition features substantial improvements in performance, security and functionality. InnoDB offers the standard ACID transaction features, as well as referential integrity support. InnoDB is included by default in most binary distributions from MySQL AB.
