The paper details current inadequacies in the hosting arena and how the CloudLinux Operating System (OS) addresses these issues. It explains how web hosts can double the density of their shared hosting servers while simultaneously improving server stability. Key findings include: 46.6% of web hosts reported they experienced downtime due to a lone site at least a few times a month; Frequently a single site or a very small number of sites utilize a disproportionate amount of resources: Top 1% of sites are responsible for 39% of the static requests (on average) to the server Top 5% of sites are responsible for 65% of static requests (on average) to the server On 25% of the servers analyzed, top 1% of the sites are responsible for 50% or more of dynamic requests to the server Reasons for server spikes which can bring down an entire server can include: One badly executed script on one site New software introduced to a site
"Linux is an operating system (OS) that is a popular option among many types of users. It is a free OS, stable, with a high level of familiarity, solid performance and good vendor support. Its advantages have allowed it to garner 60% of the web server market which means is it a popular choice among web hosts as well. Yet despite the obvious advantages, Linux is not fully optimized for web hosts because it was never designed specifically to address the unique set of requirements for this market."
