Maintaining Site Performance on Shared Hosting
Thousands of sites could be hosted on one physical server, and just one application could affect all other sites hosted on the server. Shared host providers must be diligent with monitoring and performance tuning on these servers to ensure that applications run smoothly and don’t have malware running on them. With the right tools, shared hosting providers can improve site performance for customers while boosting overall revenue.
How To Fix A Slow Site With PHP X-Ray

When a web site slows down, there’s usually a problem with its content management system. To restore its performance, it used to be necessary to delve into its WordPress, Joomla, or Drupal installation and diagnose the problem by hand. Now, on servers that run CloudLinux OS+, performance problems can be identified immediately using a new tool called PHP X-Ray.
What is DPDK, and What is it Used For?
The Data Plane Development Kit (DPDK) is an open-source software project with a vibrant community of development contributors. Because it is open-source and free, a large portion of the tech industry involved in microprocessor research and development are working to improve DPDK with each release update. This includes computer scientists and researchers from Intel, IBM, and Cisco, among other industry leaders.

Introducing CloudLinux OS 8 with cPanel and Plesk Compatibility
In February 2020, we released CloudLinux OS 8 with the 4.18 Kernel. The rollout was a success as users experienced reliability and full update support via CloudLinux. Now, we are pleased to announce full compatibility with cPanel and Plesk control panel interfaces. While it showed great performance and strong workability on the DirectAdmin servers, the latest compatibility update adds much-needed GUI support, something web hosters will surely appreciate.

PHP X-Ray for End-Users Released in Beta
- About PHP X-Ray.
- How it works.
- For Administrators.
- For End-Users.
- Documentation.
- To test out PHP X-Ray with a free CloudLinux OS+ trial.
When your website performance fails, it’s usually an issue with the Content Management System (CMS) or a poorly optimized plugin, but how does a webmaster analyze the issue?
You could go through the code, disable plugins and even reinstall the CMS software, but these solutions could create downtime and root-cause analysis could still come up with nothing. Instead of tediously combing through web application code and plugins, CloudLinux PHP X-Ray lets you monitor and diagnose performance in CMS applications such as WordPress, Joomla, or Drupal without affecting uptime.

Announcing Open-sourced & Community-Driven RHEL Fork by CloudLinux
CentOS is a fork of Red Hat Enterprise Linux (RHEL) and undoubtedly a popular choice to deploy on production servers because of its rock-solid stability and compatibility. But, now with CentOS Stream, Red Hat just killed CentOS as we know it. And as expected, people started to fork Red Hat to give a viable community-based alternative to RHEL.

CloudLinux OS 6 has officially reached its End-Of-Life

CloudLinux OS 6 has officially reached its End-Of-Life on November 30, 2020. Software that reaches its end-of-life is no longer supported by developers, which means that you no longer receive critical security patches, updates, or feature changes. Unsupported software that receives no security patches could be vulnerable to future exploits, meaning your servers and devices could be targeted. With extended CloudLinux OS 6 support, you still get patches and updates as usual until 2024, giving you plenty of time to update to CloudLinux OS 7 or 8.
