Our Servers

Our Servers

We’ve invested a lot of resources to increase the speed, stability, and reliability of our servers.

For redundancy and speed, we’ve create a powerful virtualised cloud infrastructure using a VMWare High Availability cluster and Dell R620s with a centralised ISCSI Compellent SAN with 40K IOPS.  If a physical hardware node fails or is running slowly, our cluster will automatically migrate the servers running on it to another physical node.

We also use a custom Linux configuration that surpasses the majority of shared web hosting providers—before we roll out new a server, we perform over 200 tweaks to the operating system, file system, and control panel.  We are also able to adjust server settings like RAM and CPU without restarting our hardware, which allows us to offer better stability and uptime.

Plus, we use CloudLinux for our operating system and LiteSpeed for our web server:  by combining these premium applications, we’re able to offer speed and reliability you won’t find with traditional web hosting providers.

CloudLinux for a Virtualised Shared Hosting Environment

For increased speed and stability, we use CloudLinux, a premium operating system.

With traditional shared hosting, a number of customers are placed on a server with very few (if any) limitations on the processing power they can use.  Without limitations on processing power, a single user can monopolize an entire shared server, resulting in slow load times and decreased stability for other users.

At Evohosting, we use CloudLinux, a premium operating system, which prevents a single user from using more than their fair share of a server’s CPU/RAM.

CloudLinux provides every customer with their own Lightweight Virtual Environment (or LVE)—an LVE allocates a certain amount of CPU/RAM for each hosting account, so no one user can impact the performance of other accounts due to excessive CPU/RAM usage.

LiteSpeed Web Server

For better speed and reliability, we use LiteSpeed, a premium web server application.

Apache, a free web server, is the industry standard for traditional shared web hosting, but it is by no means the fastest web server available.  Unfortunately, Apache is easily overloaded, resulting in slow and unstable performance.

At Evohosting, we use LiteSpeed, a premium web server application capable of processing requests up to 6 times faster than Apache.  LiteSpeed includes multiple layers of protection you just won’t find with Apache, making LiteSpeed a faster and more robust web server.

By combining LiteSpeed with CloudLinux, we provide every customer with their own Lightweight Virtual Environment and access to a web server that is up to 6 times faster than Apache.

Reading and Writing

For better speed, we mount all hard disks in NOATIME mode.

Traditionally, when a file is read from a hard disk, a ‘last accessed’ time is written to the file so the server knows when a file was last accessed.   Writing to a file takes 3 times the resources and time of reading a file, which means a busy webpage can unnecessarily impact the speed and performance of a site and server.   While this practice hinders performance and serves no real purpose, most web hosts leave this feature enabled.

At Evohosting, we mount our drives in NOATIME mode, so a file isn’t written to every time it’s read.  This practice improves server and site performance, because the file system should be able to handle three times the number of read files as a traditional file system with another hosting company.  This simple practice significantly improves speed, yet it hasn’t been embraced by a lot of web hosting providers.
