Today, I will talk to you about how much concurrency a CVM can support. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something from this article.

Concurrency is a parameter in the server. People usually measure the capacity of a web server, which is the number of requests it can handle per unit time.

The number of concurrent users is the number of users who send requests to the CVM at the same time, which is affected by many factors and does not have a fixed exact value.

The maximum number of concurrency has a certain interest premise, and it is a measure of the expected interests of the user and the server. Generally speaking, the server maintains a relatively high throughput, and the number of concurrency when the user is satisfied with the waiting time can be determined as the maximum number of concurrency.

In the case of a large number of concurrent users, what kind of concurrency strategy for cloud server leasing is the key to affect the maximum number of concurrent users.

CPU concurrent computing

The reason why a CVM can handle multiple requests at the same time is that the operating system designs multiple tasks through a multi-execution flow system to take turns using system resources, including CPU, memory, IO, and so on.

The length of CPU time slice should be specifically weighed. If the time slice is too short, the time waste of CPU in process switching is relatively large. If the time slice is too long, then the real-time and interaction of multi-tasks can not be guaranteed.

The higher the system load, the busier the CPU, and the less able it is to meet the needs of all processes. The system load is calculated based on the average number of processes ready to wait in the run queue per unit of time. When the ready process in the run queue does not need to wait, you can immediately get the CPU indicating that the system load is low and the system response speed is fast.

After reading the above, do you have any further understanding of how much concurrency a CVM can support? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
