How many CPUs and RAM do I need for 20 sites?

mattnz · Jul 18, 2016

We have around 20 websites (built base on Wordpress cms) with 300+ visitors per site per day and we wanted to move to a new VPS. How many CPUs and RAM do I need to use for these 20 sites to make them run smoothly on the VPS?

Please share your suggestions and optimizing methods for the server if needed.

You have two solutions :

1) With a control panel like Plesk or cPanel. And it will require more resources. So at least 2vCores and 6-8GB RAM.

2) Setup the VPS without a control panel. Your WordPress should be faster with a proper configuration, and it should not require more than 1vCore & 2-4GB RAM.

VirtuBox is correct, if you decide to go for option two, I do suggest +4GB RAM so that you can place proper caching systems in place and take full advantage of the VPS.
Installing a control panel will make your life easier if you dont know how to run your wordpress without a control panel and also will have its own features. If you decide to go for a control panel, choose plesk as it will be free for you while Cpanel could possibly cost a little below half of what your VPS would cost.

For me i will go with a server of Ram: 8GB, Processor: 4 CPU Cores, just in case of feature increment in traffic and site files and more site that might be created.

I would suggest you to go with a a managed vps plan as it will have cPanel included in it. Most providers have cPanel included in their managed plan.

Also try going with something with 4 GB RAM and 4 core.

Do you have any particular budget in mind for the vps?

The CPU and RAM requirements for hosting 20 sites depend on factors like site complexity and traffic. For moderate traffic and standard websites, 4 CPUs and 16GB RAM should suffice. Evaluate specific needs, consider scalability, and consult hosting providers to ensure optimal performance for your multi-site hosting.

The CPU and RAM requirements for hosting 20 websites depend on several factors, including the complexity of the websites, expected traffic, and the technology stack used. Generally, for a moderate load, you might consider a server with at least 4-6 CPU cores and 8-16 GB of RAM. However, it's best to consult with a hosting provider or a sysadmin to determine the exact specifications based on your specific needs and usage patterns.

For 20 Wordpress sites with 300+ visitors each, you would need at least 4 CPUs and 16GB of RAM to ensure smooth performance on the VPS.

To optimize the server, you can use caching plugins like W3 Total Cache, optimize images and scripts, minimize CSS and JS files, and regularly update plugins and themes to ensure better performance. Additionally, consider using a CDN to distribute the load and reduce server stress.
