With the launch of various host products, there are various problems in the server . Since the virtual hosts are running at the same time, it will put too much pressure on the server, which will cause the speed of the server to become slower and slower. I will share with you below. Let's take a look at the reasons why the server is getting slower and slower and how to fix it.
1. The virtual host occupies too much resources, and the virtual host resources need to be migrated
As your workload increases and the number of virtual machines proliferates, you may find that you need to migrate a problem-causing virtual machine to another host, or offload a "good" virtual machine to another host in order to save resources for the needs of virtual machine to free up resources.
2. The physical resources of the server are not enough
When you notice that your server is sluggish, the first thing to do is to check the physical resources of the server. Sometimes there are too many server processes, causing the disk to be full, and the server cannot be brought back, so the response will be slow. At this time, you only need to add more memory or add another processor.
3. The load is too large and needs to be adjusted in time
Know and be familiar with your own server, understand where the limitations of the server are, how much processing power and storage capacity it has. The slow response of the server may also be because the process you are running exceeds the capacity of the server. At this time, it is necessary to correct and adjust the load to ensure the normal operation within the processing capacity of the server.
Solution:
1. Clean the dirty web
A dirty network is one in which packets are lost, reordered, or fragmented, which can slow down server performance, resulting in poor server performance and excessive server load. Different running virtual machines and guest operating systems share processor time. If switching from one virtual machine to another virtual machine, there will inevitably be delays. If the configuration is incorrect, network packets will be delayed and blocked by the underlying network. Stack discards; once you hit a tipping point, performance degradation is not only noticeable, but catastrophic.
2. Make sure it's the server that's causing the problem
Many performance problems that seem to come from the server level are often caused by problems at the network, database, and storage system levels. If there is a delay problem, we first look at whether the delay first occurs at the server, or at the network or client level.
3. Get rid of cumbersome and cumbersome applications
The slow response of the server may also be caused by an application. The application may be too cumbersome and cumbersome. When writing such an application, it does not use large frames containing a large amount of data and sends a relatively small number of frames, but uses the smallest frame. , so in the end, you have to send a lot of data back and forth frequently to complete the tasks that larger frames can complete, resulting in slow server response. So access to large frames with large amounts of data is faster, safer and more convenient.
Of course, there are many reasons for the slow server speed, and the solutions are also various, and the specific situation is analyzed in detail!
