Server latency (also known as network latency or ping latency) is the time it takes to send a request from a client computer to a server and receive a response from the server. For US servers, latency depends on many factors, such as your location, network quality, and server location and performance. Usually, the delay time should be between tens of milliseconds (ms) to hundreds of milliseconds.

Specifically, the following are some latencies that are generally considered normal:

In the same city or region in the United States: the delay time is usually between 10-30ms.

In different states or regions in the United States: The delay time is usually between 30-70ms.

Across the entire United States: Latency is usually between 70-150ms.

It should be noted that this is only a reference value under normal circumstances, and the actual delay time may vary due to factors such as network congestion, server load, and router configuration. If your server latency is higher than normal, you may need to check your network connection, optimize your application, or choose a different server location.

How much is the delay in China's access to the US server?

Latency for China to access a US server depends on a variety of factors, including your location, the quality of your internet connection, the location and performance of the server, and more. Due to the long distance between China and the United States, there may be a longer delay in network transmission.

Under some of the best network connection conditions, China's server latency for accessing the United States can be between 150-250 milliseconds (ms). In some less-than-ideal situations, the delay may be longer. In addition, some network services may take optimization measures, such as using CDN, accelerator and other technologies, to reduce latency and increase network speed.

It should be noted that delay time is not the only consideration. Network stability, bandwidth speed and data security should all be taken into consideration.
