It is obvious that the CPU of the VPS in the Dallas computer room is AMD RYZEN 9 3950X, clocked at 3.5GHz, and the hard disk I/O is currently 1.4GB/S. The webmaster turned on BBR. Here’s a quick mention: There was a problem with the Ubuntu 20.04 template during the webmaster’s test, and it couldn’t be used after installation. However, there was no problem with 18.04.

FIO conducted a detailed read and write test on the hard disk. The data results are as follows:

Everyone is very concerned about how much bandwidth Xiaoji can run, especially how much it can run in the environment of mainland China. Let’s use speedtest.net’s mainland China three-network node to run the uplink and downlink. The data is as follows:

Due to the network explosion during the evening peak hours in mainland China, we will also test it here. Let’s compare the effect during the day, especially the attenuation in the telecommunications area is particularly serious:

Test results of other nodes in Asia:

Let’s take a look at the effects of European and American nodes tested by iperf3:

The files stored on the VPS can be downloaded directly using the Chrome browser. Let’s see how fast it is (the webmaster is Guangzhou Telecom):

The speed during the evening peak period is only 4.8MB/S:

Pay attention to the delay situation. There are more than 170 monitoring nodes around the world below:

Outbound telecommunications, direct connection to backbone network:

China Unicom outbound, backbone network docking cogentco from Los Angeles:

On the outbound journey, CMI International Network docked with Cogentco from Los Angeles:

Return to China Telecom:

Towards Beijing, take cogentco from San Jose to connect to the backbone network;

In the direction of Shanghai, take level 3 from San Jose to connect to the backbone network;

In the direction of Guangzhou, take Verizon from Los Angeles to connect to the backbone network;

Return to China Unicom:

For Beijing and Shanghai, Verizon connects to China Unicom’s AS4837;

In the direction of Guangzhou, cogentco connects to China Unicom AS4837;

Return to mainland China: Directly connect back to the node in Los Angeles or Seattle on the West Coast of the United States

Streaming media test-TIKTOK (only represents the current IP segment):

Other streaming media test results:

Other performance test results:

A rough summary:

The performance is really great, whether it is hard disk I/O or CPU running scores, they are all awesome;

In terms of network, China Telecom uses mixed lines such as Verizon, Level 3, and Cogent for its backhaul, which is not effective during evening peak hours; China Unicom always connects to AS4837 last, and China Mobile always returns directly from the mobile node on the West Coast of the United States. Generally speaking, if you have to buy Dallas, China Unicom and China Mobile may have better results than China Telecom, and China Unicom will be better than China Mobile.
