Swappiness is the kernel parameter that defines how much (and how often) your Linux kernel will copy RAM contents to swap. This parameter's default value is “60” and it can take anything from “0” to “100”. The higher the value of the swappiness parameter, the more aggressively your kernel will swap.
What is CentOS?
CentOS or Community Enterprise Operating System is a community driven enterprise-class GNU/Linux distribution that uses the upstream sources of Red Hat Enterprise Linux as it basis. This RHEL fork is fully compatible with Red Hat's system, but it is free of price, certification requirements and support services. This fact quickly raised the popularity of CentOS among server administrators and other demanding sectors of the corporate environment, so the project ended up being acquired by Red Hat in 2014, who also hired the head developers of the project. CentOS however remains independent as an entity, focused in the development of open source solutions and led by their own governing board.
Why use CentOS?
As CentOS is basically a RHEL fork, it boasts top notch security features that meet the increased needs of web servers in that sector. Red Hat employs a large team of experts that work on locating and filling security holes in a daily basis. These fixes are then circulated through critical updates that CentOS receives regularly. This procedure ensures the utmost level of security that CentOS users enjoy without spending a nickel.
Another factor that is critical for enterprise grade systems is their stability. Being a RHEL fork, CentOS features great operational rigidness and solid systems implementation that are reliable for any use case. CentOS is known for using older and more stable and tested versions of software packages that are performing more predictably and feature very low failure and bug rates. All packages are carefully selected and tested for their interoperability and proper functionality, so while CentOS may not feature the latest and greatest software, it will certainly allow you to work without any nasty surprises.
The third critical factor that makes CentOS unique among enterprise level operating systems is the wide spectrum of hardware architectures that it supports. CentOS can work seamlessly on 32 or 64-bit Intel and ARM systems, PowerPC (Apple Macintosh), IBM eServers, DEC Alpha and SPARC.
