Hepsia Advanced Features
The Advanced tab grants you quick access to a set of advanced features, among them the Memcached distributed memory object caching system and the Varnish Cache web application accelerator, which will help you optimize your web sites and applications without the need to log out of the web hosting Control Panel. Depending on the hosting plan, these features are either included by default or are offered in the form of easily gettable upgrades. InnoDB and NodeJS support is offered as well.
Varnish
Varnish Cache is a web application accelerator also famous 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 very, very fast and will boost the speed of your site. One of the major pluses of Varnish Cache is the flexibility of its principal configuration mechanism, VCL, which permits you to choose how incoming requests should be handled.
Memcached
Memcached is a generic memory object caching system for increasing the speed of dynamic database-powered web sites. 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 object caching system uses a client/server architecture. The Memcached distributed memory object caching system is employed by some of the most traffic-heavy sites on the Internet and is supported by popular web applications like Joomla and WordPress.
Node.js
Node.js is a software system for writing scalable network applications. Built on Chrome's JavaScript runtime, Node.js uses an event-driven, asynchronous input/output model that makes it lightweight and effective, suitable for real-time content-intensive network apps. Node.js uses Google's V8 JavaScript engine, libUV, and several built-in libraries.
InnoDB
InnoDB is the default database engine for the MySQL open-source database management system. A database engine is the primary software component that a DBMS uses to create, read, modify and delete data from a database. Its latest edition features significant improvements in efficiency, stability and functionality. InnoDB provides the standard ACID-compliant transaction features, along with referential integrity support. InnoDB is included by default in most binary distributions from MySQL AB.
