Still hosted with a cPanel based server which makes your websites crawl to a halt? Look no further.
The Citrus stack is a panel-less high-performance server stack with bleeding edge web technologies built in. It gives you ultimate speed out of your VPS or dedicated servers.
The Citrus stack web server environment is based on a fine-tuned configuration of open source software. We have decided to give it a special code name to distinguish it as high-performance server stack for the modern web. GetPageSpeed can provision a server from any hosting provider with the complete Citrus Stack.
