The Advanced tab grants you quick access to a set of advanced features, among them the Memcached memory caching system and the Varnish Cache web accelerator, which will help you optimize your websites and applications without needing to log out of the web hosting Control Panel. Based on the website hosting plan, these features are either included by default or are offered in the form of easily gettable upgrades. InnoDB and NodeJS support is available too.
Varnish Cache is a web application accelerator also referred to as a caching HTTP reverse proxy. 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 increase the speed of your web site. One of the important advantages of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which permits you to choose how incoming requests should be dealt with.
Memcached is a generic distributed memory caching system for boosting the loading speed of dynamic database-driven websites. It is used to decrease 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 distributed memory caching system is used by some of the most popular sites on the Internet and is supported by popular Content Management Systems like Joomla and WordPress.
InnoDB is the default storage engine for the MySQL open-source relational database management system. A database engine is the underlying software component that a DBMS uses to create, retrieve, update and delete data from a database. The latest version of InnoDB features considerable improvements in performance, dependability and usability. InnoDB provides the standard ACID transaction attributes, along with declarative referential integrity support. InnoDB is included by default in most binaries distributed by MySQL AB.
