Simply evaluate the classic cloud of dogyun - American Unicom AS4837 series

How about dogyun ？ dogyun What about? Dogyun has not only cn2+cu2 series ECS in the United States, but also 1Gbps large bandwidth Unicom AS4837 line ECS, which is also a classic ECS. What is the effect of American Unicom AS4837? What is the gap between morning and evening peak hours? How about the effect of telecom cn2? With these questions, we have this evaluation. The data is for reference only!

We can see directly that the CPU is amd ryzen 9 3950X, with the main frequency of 3.5GHz. It seems that the server is in the cera machine room, and the webmaster has turned on the BBR. Since the official default limits everyone's use of hard disk I/O, we tested it roughly in the beginning of 100Mbps:

FIO tests the read/write status of the hard disk again:

The speedtest.net node helps us test how much the chicken can reach up and down. From the perspective of nearby nodes, the bandwidth is at least 1Gbps. The highest uplink in China can reach about 500Mbps, and the downlink can reach 900Mbps:

In the same test, let's see the data effect during the peak hours of the night:

The uplink and downlink test results of some nodes in America, Europe, Asia, Africa, etc.:

Some nodes in the Asian region test up and down:

The general results of iperf3 running in Europe and the United States:

The files stored on the test chicken can be downloaded directly from the Chrome browser. The general effect of Guangzhou Telecom is as follows:

Guangzhou Telecom downloads at about 5.8MB/S during the evening peak:

Delay test data of multiple nodes in domestic three networks:

Telecommunication journey, direct telecommunication:

China Unicom, direct:

Mobile travel, international CMI direct:

Return trip to China Telecom: all of them leave the computer room and go to China Unicom AS4837 to return home, and transfer to China Telecom

Return to China Unicom: the computer room comes out and China Unicom AS4837 returns home

Return trip to China Mobile: go out of the computer room and directly connect with AS4837 to return home, and transfer to China Mobile

TIKTOK Streaming Media Unlocking Test: America, OK

Cross regional streaming media platform unlocking test:

North American streaming media unlocking test results:

Some performance test data:

To sum up ：

The overall performance of the server is very strong. After all, it is a new product of AMD, and the hard disk I/O limit is official;

Network: direct connection to three networks; On the return trip, the three networks forced China Unicom AS4837 to return home and transfer their own networks in China. From the perspective of effect, it is relatively good on the whole. It is inferior to the high-end expensive CN2 CU2 and much better than the international BGP. The cost performance is still very good!
