Difference between share and dedicated CPU


I'm wondering if there's a difference between a dedicated and shared CPU VPS, from my understanding, it is cheaper to get a shared CPU, what are the benefits of a dedicated CPU VPS and the risks involved when using a shared CPU VPS?

Here are some brief differences, and observations I have made in my own dealings between the two.

First, in a shared CPU plan, your time of the CPU is shared with others. As a result, you will encounter what's known as CPU Steal, which normally isn't a problem, unless you're on a host with noisy neighbors. No one can steal your CPU time on a dedicated CPU plan, which will allow your Linode to operate with more consistent performance.

In my own personal experiences, if I run a process at real time priority, a shared CPU plan will eventually lock up my Linode to the point where it will become practically unresponsive. A dedicated CPU plan doesn't have this problem for me.

Also, you may wish to review this guide, which could help you in making a decision on which plan you want to choose.

I hope this was helpful for you.
