If you want to improve the network speed, in addition to increasing the network bandwidth from the periphery, you can also try to reduce the packet size of network transmission. For example, you can use some paging methods to get a list of data.
In addition, you need to guide users from the interface layer. Sometimes good artists can be half efficient, and their interfaces are not slow. For example, we usually copy a disk file, and sometimes we copy a large file. If Windows doesn't have that scroll bar, you will crash, but the effect of having a scroll bar is completely different.
