We recently upgraded our account to VPS.

I have been looking at Server Load in the WMM panel, and it is currently reading around 0.51.

At what point to we reach maximum processor usage? Is the max 1.0 or is ti a different number?

Thanks-

Hi MBGreen,

In order to know when you're running your server at 100%, you need to know how many processors are on your machine. Your server's load average is basically an indication of how many processors you are using.

For example:
If you have 1 processor and your server is at a load of 1, you're running at 100%. If you have 2 processors and your server load is at 1, then you're running 1 out of the 2 processors at 100%, which means you're at 50% utilization. Finally, if you have 16 processors and your server load is at a 4, you're only running at 25%. It can get a little more complicated than that, but that's the basics.

<a href='http://www.inmotionhosting.com/vps_hosting.html'>VPS servers</a> are a little different. My VPS server shows that I have 16 processors, so theoretically my server load would have to be up to 16 before I reached 100% utilization of the server. Because you're in a VPS environment, it doesn't work exactly this way however, because things are virtualized.

I touched base with one of our System Administrators and was informed that in the VPS environment you'll want to run your server below a 1. A server load of 1 - 2 is considered high, where a server load of 3 - 5 is reaching critical levels. These numbers again may flucutate based upon which server your VPS is on and how many processors are on that server.

I suggest keeping your server load below 1. For your particluar server, it would be best to email our System Administration team so they can look at the specific details of your account and provide you with a more direct answer.

I hope this helps! Feel free to post a comment at the bottom of this page if you have any follow up questiosn, I'll be more than happy to see what I can do further to help.

Thanks,

Hello,
I found really helpful your answer and would like to ask you for advice for my server.
I have Dedicated server running on CloudLinux (12CPUs) with the following configuration:
RAM: 64 GB DDR4
Hard Drive: 2 x 512 GB NVMe Gen3 x4
(Software-RAID 1) SSD
Intel® Core™ i7-8700 Hexa-Core
incl. Hyper-Threading Technology 12MB SmartCache 4.60GHz

What would you advice me about the Server Load? When to be worried? How far can get?
Buy your experience how many accounts by average judgement can host this server as shared hosting server?

Hello Thekoko,

Trying to determine how the load will be on a system which we do not have access to and not configured by us will be very difficult. The load handling depends on both the software and hardware aspects of the installation. My suggestion is that you run it and then try simulating loads on it. There are many options out there that allow you to test. Try searching for "webserver stress tool" or "load impact for webservers" and you will find many options that can help you determine how your hardware and web server setup will act when it's being used. Our data and reflections of the load on a server reflect the years of tweaking both the hardware and software used for our hosting services. Providing you a similar comparison on your hardware would not be accurate and may provide you with false assumptions. I hope that this is clear. If you have any further questions or comments, please let us know.

Kindest regards,
Arnel C.
