Asymmetric switches are still commonly used, so I have studied how to use asymmetric switches to improve network performance. Here I will share with you, hoping to help you. Vswitches can be divided into two types based on the speed of each port of a vswitch. Symmetric switches and non-symmetric switches. Symmetric switches provide exchange connections between ports with the same bandwidth. For example, all

When an application is running, there will always be data that needs to be accessed frequently and does not change frequently. If the data needs to be read from the database or external file system every time you obtain the data, the performance will certainly be affected.Therefore, the common practice is to cache this part of the data, as long as the data does not change, the performance will be greatly im

This network interface is very fast, and in order to improve performance, the server intentionally does not support authentication or secure communication. However, this should not limit deployment options. The memcached server should exist within your network. The practicality of the network interface and the ease with which multiple memcach
