Hepsia Advanced Features
The Advanced tab gives you swift access to an array of advanced tools, among them the Memcached memory object 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 Control Panel. Depending on the website hosting plan, these features are either included by default or are offered in the form of easy-to-get upgrades. InnoDB and NodeJS support is offered as well.
Varnish
Varnish Cache is a web application accelerator also famous as a caching HTTP reverse proxy. You can install it in front of any web server that speaks the HTTP protocol and configure it to cache the content. Varnish Cache is really, really fast and will increase the loading speed of your site. One of the main merits of Varnish Cache is the flexibility of its domain-specific language, VCL, which enables you to choose how incoming requests should be handled.
Memcached
Memcached is a generic distributed memory caching system for increasing the speed of dynamic database-driven sites. It is used to lower 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 system uses a two-tier architecture. The Memcached memory object caching system is employed by some of the most traffic-hungry sites on the web and is supported by famous CMSs like Joomla and WordPress.
Node.js
Node.js is a software system for writing scalable network apps. Written in JavaScript, Node.js uses an event-based, asynchronous I/O model that makes it lightweight and efficient, excellent for high-performance content-intensive apps. Node.js uses Google's V8 JavaScript engine, libUV, and several in-built libraries.
InnoDB
InnoDB is the default database engine for the MySQL open-source database management system. A database engine is the main software component that a DBMS uses to create, read, update and delete data from a database. The latest release of InnoDB features considerable improvements in efficiency, security and usability. InnoDB offers the standard ACID-compliant transaction properties, along with referential integrity support. It is included by default in most binary distributions from MySQL AB.
