This article will explain in detail the difference between CVM 2 core and 4 core. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

CVM 2-core 4-core refers to whether the CPU configuration of the CVM is 2-core or 4-core. CPU is the central processor used on the server, is the "brain" of the computer, and is the primary indicator of server performance.

The main difference between CVM 2 core and 4 core is that the server processing speed is different, which also has an impact on the website opening speed. Of course, the website opening speed mainly depends on the bandwidth quality.

For the difference between a 2-core and 4-core CVM, first of all, it is important to know that the impact of the CPU processor of the general CVM on the website is the number of concurrency that affects the connection, that is, the limit of IIS. When visiting the website, the biggest impact on the access is the bandwidth, of course, memory will also have an impact.

How to avoid 100% occupancy of CVM CPU

Generally speaking, single-core and multi-core for some small and medium-sized websites, the difference is not obvious, only large websites will reflect the difference. When there are a large number of visitors, if a single core reaches the maximum number of connections to the CVM, then the cpu resources will not be enough, and other users will no longer be able to access the CVM website.

Multi-core CVM is the computing core of multiple servers for resource integration. When one CPU core of the CVM reaches its limit, the resources of the other core cpu will be used, so that the cpu100% will not occupy a similar situation.

If you choose a CVM, the initial cost will not be too high. For example, your personal blog, personal website or small business website will not have too many visits or peak concurrency, but if you put a forum program, for example, when there are a lot of people online, you can't think about it this way.

In fact, CVM users do not have to worry about the shortage of server cpu resources, because CVM leasing can be upgraded freely, that is, when the number of website visits increases, the configuration can be adjusted at any time.

CVM users can freely choose CPU, memory, data disk, bandwidth and other configurations according to different needs. They can also upgrade bandwidth without downtime at any time, and upgrade CPU and memory within 1 minute to support the continuous development of the business.

This is the difference between CVM 2 core and 4 core. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
