For example: https:// /vps/meiguo-vps-tuijian

This test used 2G memory, 2 cores, 40G SSD, and 100M bandwidth. By default, the webmaster turned on BBR, and the average I/O was about 750MB:

FIO test, please pay attention to the key point of comparison: 4K:

The uplink bandwidth and downlink bandwidth of the three-network multi-node test VPS in mainland China. Since speedtest has almost no mobile nodes in mainland China, it is difficult to compare. Here we mainly look at China Telecom and China Unicom. What you can see is China Telecom. China Unicom and China Unicom both have uplink speeds of 100Mbps, and overall the downlink bandwidth is basically 200Mbps:

In the iperf3 test, the uplink effect in Europe and the United States is basically perfect, almost full, and the downlink is almost the same. After all, the bandwidth of our VPS is not exclusive:

The following is the speed at which Guangzhou Telecom’s Chrome browser downloads files on the VPS. For an uplink bandwidth of 100Mbps, this speed is close to perfect. Don’t think about exclusive bandwidth:

Let’s take a look at the effect of collecting the package:

Test results of more than 120 nodes on ping.chinaz.com in mainland China:

Telecom's outbound journey takes the backbone and goes directly to the computer room:

China Unicom's outbound journey is from the backbone network to the telecom backbone export to the computer room:

The outbound mobile journey is still bone-fixed and is directly connected to the computer room via the CMI network:

Return to China Telecom: back to Beijing, Shanghai, and Guangzhou, the same thing is that we found that China Unicom always takes AS10099 to Hong Kong, and then unifies AS9929 to the mainland, and then they start to go their separate ways.

Return to China Unicom: AS10099 goes to Hong Kong, then AS9929 goes to the mainland, and then connects to AS4837.

Return to China Mobile: unify AS10099 to Hong Kong, then AS9929 to the mainland, and then connect to AS4837. At this point, the China Unicom link is completed, and then connect to their respective mobile phones.

To summarize: for the outbound journey, basically all channels are directly connected to the main backbone; for the return journey, it is basically China Unicom International AS10099 back to Hong Kong, and then AS9929 back to the mainland, and then China Unicom continues to use AS4837, and China Telecom may use AS4143, The mobile network may be AS9808. In other words, the outbound network is an ordinary direct connection, and the return network borrows high-quality links such as AS9929+AS4837.
