I believe that many users who rent foreign servers have encountered this problem. Usually, because they are too far away from China, they cannot compare with domestic servers in terms of access speed and delay. So how to solve the problem of high delay and slow speed of foreign servers? ? Let's chat together.

What is the reason for the high latency of foreign servers?

The average delay of accessing domestic servers in the United States is about 120ms-180ms, the average delay of Korean servers is about 40ms-90ms, and the average delay of Japanese servers is about 30ms-70ms. The delay of the server is too high. In addition to the distance factor, there are also local network, line, Nodes, routing, etc., such as slow local network, line congestion, too many nodes, data transmission needs to jump to multiple nodes, resulting in slow speed and high delay. This is also one of the main reasons why accessing foreign servers is often slow.

How to solve the high latency of foreign servers?

The main reason for the high latency of foreign servers is discussed above, so we can solve the problem in a targeted manner. This is also the mainstream method to solve the problem of slow server speed and high latency, that is, CDN nodes and BGP+cn2 lines. The website is cached to nodes in various regions, and user access will be adjusted to the nearest cache node, thereby improving the speed of user access to the website. CDN solves the problem of too long distance, and the BGP+CN2 line is directly transmitted from the foreign computer room to the domestic , reducing the high delay caused by too many jump nodes. In addition, some servers with slow speed can also be solved by increasing bandwidth. Therefore, if the delay of foreign servers is too high and the speed is too slow, it can be solved by CDN acceleration, BGP+CN2 line, and bandwidth. .

At present, the solution to the high latency and slow speed of foreign servers is to configure CDN acceleration and BGP+CN2 lines. If the latency is still high and the speed is slow, you may try the domestic record-free Hong Kong server, or the closer Japanese server or Korean server. , to physically shorten the distance, thereby reducing latency.
