Using the current version of cpanel and Centos 7.8, is cpanel optimized for Intel Xeon dual processor, 8 core 16 threads? Or any number of cores and threads? I ask because I was watching a review of amd's 3900 X single processor and an Intel 9900 K single processor showing some impressive scores.

I also learned that Intel has over 15,000 developers and coders that work with software developers to optimize their software for the Intel chipset. Does cpanel get this free assistance from Intel or even from AMD?

I'm trying to avoid asking the question of which processor is better. For 22 years I've run a combination of chips with the Athlon 64 dual processor being very good at its time and of course the Intel Dual Xeon multi-core multi-threaded.

So I guess the bottom line question is which CPU is cpanel run best on for a web server hosting hundreds or thousands of sites? Does the operating system such as Centos make a difference or are we talking about EasyApache or Lightspeed being required?

Thanks in advance.

Hi @Server Pros

I don't know the official answer to these! I'll check in with our development team first thing in the morning to see what I can find out for you.

IF you're hosting hundreds or thousands of sites you may want to look at an alternative like litespeed, you'll find better performance with a larger number of sites though it is not mandatory.

Thank you for your reply. Litespeed is far too expensive. They charge you based on the number of cores or threads or both and the number of CPUs. It's just far too expensive. It's cheaper just to put a new server in and limit the current server to several hundred sites. I run dual Intel Pentium 3.0 GHz 8 core processors.

But if the software is not optimized for Intel or AMD it is not beneficial to be running dual processors. If you run dual processor son until and have say 32GB of RAM that Ram is divided in half. 16GB per processor. I don't see any reason why cpanel or even plesk for that matter would not be optimized. The optimization is not in the OS oh, it's in the application.

Hello,

I received an answer to the inquiry for this yesterday. The short answer is no, the long answer is that as we are a control panel software, our responsibility is to manage the software on the server, when not managing this the idea is that we aren't consuming resources. The work to ensure that software is optimized for an operating system is better suited to the creators of Apache, Exim etc. the pieces of software that do interact more directly with the OS.

I hope this helps answer the question and please let us know if you have any further.

If I understand your question correctly, your asking the wrong people. In the overall usage of your server cPanel and WHM more than likely account for basically no usage. What (to me) seems a lot more logical to ask is:

- Is Apache optimized for ###
- Is MySQL optimized for ###
- Is Exim optimized for ###

Those processes are what drive the load on your server. Since (for the most part) cPanel is just using the upstream packages, they won't really be able to answer.
