Simple evaluation of dogyun (dogyun) cloud server of German CUII route (star product of China Unicom)

Let me test a German cloud server from dogyun. After all, the vast majority of European machines coming to mainland China have poor connections, and there are too few access to high-end connections. According to the official statement, Gouyun's German cloud server is connected to CUII (we sometimes have different names, but they all mean the same thing, such as CU2, AS9929), and is supported by China Unicom's obvious products (independent links), with high speed The above should be good, right? The test data is published below for reference only!

The CPU is e5-2680v2, and the main frequency is quite high. After getting it, I turned on BBR directly without asking why. The official limit is on the hard disk I/O of a single cloud server. It is probably for everyone's fairness and does not want someone or some people to destroy everyone's resources. What we see is that the hard disk I/O is roughly around 127MB/S:

The detailed data of FIO test is as follows:

To what extent European cloud servers can run on mainland China’s network, let’s first look at the uplink and downlink tests of speedtest.net’s three network nodes in mainland China. Let’s talk about the default official bandwidth of this cloud server: 100M bandwidth:

Comparing the situation during the evening rush hour, the difference is actually not big:

Test the effect in other places in Asia:

The following is the situation of iperf3 running in Europe and the United States:

For files stored on the cloud server, the download speed of Guangzhou Telecom directly using the Chrome browser is approximately 8.5MB/S:

Compare the download speed during the evening peak hours, there is attenuation, but the effect is still good:

Pay attention to the delay. PING data is provided by ping.chinaz.com, which tested the results of more than 60 nodes in mainland China:

On the outbound journey of China Telecom, the backbone network reaches AS9929 and then transfers to China Unicom International AS10099 in Hong Kong to the German computer room:

On the outbound journey of China Unicom, the backbone network reaches AS9929 and then transfers to China Unicom International AS10099 in Hong Kong to the German computer room:

Move the outbound journey, then CMI, then level3 to the United States, then continue L3 to Germany:

Return to China Telecom:

Go from Germany to the Netherlands to the UK Unicom node, then connect to China Unicom International AS10099 and then transfer to AS9929 and then transfer to China Telecom AS4143. Standard China Unicom high-end line return process

Return to China Unicom:

Go from Germany to the Netherlands to the China Unicom node in the UK, then connect to China Unicom International AS10099 and then transfer to AS9929 and then AS4837 to return to China. Standard China Unicom high-end line return process

Return, move to mainland China:

Shanghai direction, normal AS9929 return route,

Beijing and Shanghai both use the telia network. There may be some problems that need official adjustment!

The last unix bench, please refer to it:

Finally, here is the general situation of streaming media unlocking, for reference only:

A rough summary:

Whether it is the outbound or return trip, the optimization is not in place. Except for Shanghai, AS9929 is almost not used;

Telecom and China Unicom are all standard China Unicom high-end line routes, and there is no problem with the speed;

Roughly speaking, mobile users need to consider this, otherwise the effect may not be good!
