Common Website Performance Issues in 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 (learn more about shared hosting security). With the right tools, shared hosting providers can improve site performance for customers while boosting overall revenue.

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.

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.

On December 8, 2020 OpenSSL released an advisory patch for a high-risk null pointer dereference vulnerability found in the encryption library’s GENERAL_NAME_cmp() function.  CVE-2020-1971 (assigned name) is the High level vulnerability that cannot be ignored. The only level higher is the Critical level which happens maybe once in 5 years.

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.
