Dogyun: A simple evaluation of the "CMI" line VPS of the "Hong Kong-CMI" data center

Dogyun's "Hong Kong-CMI" series of VPSs provide 50Mbps bandwidth, which is the largest bandwidth among Dogyun's many Hong Kong VPSs. It is estimated that many people have heard of Hong Kong's CMI line before. Everyone says it is the son of China Mobile. Some people also say that the effect of CMI is relatively average for China Telecom and China Unicom. Today we use the lowest configuration VPS of Gouyun Hong Kong CMI for evaluation. The data is for reference only!

The speedtest nodes in Asia are not much better than those in mainland China:

The effect of iperf3 running in Europe and the United States seems to be much better:
