The China server is connected with the American server, and has at least 12 nodes, mainly through the domestic export, then connecting the submarine optical fiber, then connecting the American local access port, and then accessing the computer room. No matter which area in China accesses the American server, there are at least 10 nodes. Due to different local networks, there will be different results. The speed and delay of each node of the American server can be clearly seen. At the same time, due to the capacity congestion of optical cables and the adjustment and busyness of routing nodes, the same IP in the same computer room is not always the same speed.

Reason two:

Is the server in the United States a stand-alone server or a virtual server? If it is a virtual server, because the virtual server divides the server into several virtual servers under the server technology, and these are * * * hardware, network bandwidth and so on. So once the bandwidth and network card are large, other virtual servers will be affected, so the access speed will slow down.

Reason three:

In terms of server machine configuration in the United States, the size of hard disk, processor and cpu will directly affect the speed of the server. If you choose a low-profile server for a large website, it will definitely be slow or inaccessible. There is also the development of websites and the increase of visits, and the current server configuration in the United States is not suitable. At the same time, a large number of accesses, exhausted bandwidth and insufficient hardware response, so the server access speed in the United States is slow. This phenomenon can be solved by replacing or upgrading. Of course, if you choose the right one, the access speed of American servers will be slow!
