How about Linode? [2022] Simple evaluation of Linode German data center

There are too many computer rooms to choose from for linode cloud servers. How are the cloud servers in German computer rooms doing now? Is the bandwidth still so abundant? Are there any changes to the route back to mainland China? Has the performance changed (due to switching AMD platforms)? All you need to answer these questions is one evaluation. You can check the test data yourself and you will naturally know in your mind!

The CPU models are roughly the same by default, at least for now, they are all AMD EPYC 7601; the I/O of the hard disk is currently roughly 764MB/s, and the webmaster has turned on BBR by default:

In order to view the read and write performance of the hard disk in more detail, let's try FIO to see the data:

Speed ​​is very important when buying a VPS. How much bandwidth can run is a core factor. When speedtest is started, the first node is the nearest node, which roughly indicates that the lowest uplink configuration we tested is 1Gbps (the official lowest configuration does also limit the uplink speed) 1Gbps, the maximum allocation is 12Gbps), I don’t know the specific limit on the downstream (the official explanation is 40Gbps in). The remaining nodes are all three-network nodes in mainland China. Please do your own research:

Let’s compare the situation during the evening peak and the backbone network explosion. At least the node stability of China Telecom is much worse. Compared with the daytime, the gap is too big. China Unicom is still so stable...

Test data of other nodes in Asia:

Run European and American nodes and take a look at the test results of iperf3:

The following is the file stored on the VPS. The webmaster is Guangzhou Telecom. The speed of direct Chrome download:

Tested during the evening peak period, the attenuation was close to 50%:

Latency monitoring of more than 170 nodes around the world:

On the outbound telecommunications journey, the backbone network is connected to NTT, crossing the United States from Los Angeles to Europe:

For the outbound journey of China Unicom, the backbone network is connected to TATA, crossing the United States from Los Angeles to Europe:

Moving outbound, CMI International directly reaches the German de-cix data exchange center:

Return to China Telecom:

Beijing direction: use Tata to connect the telecommunications backbone from Germany

Shanghai direction: Take Telia to China Telecom's node in Frankfurt, and then come back directly

Guangzhou direction: take cogentco from Germany to connect with the telecommunications backbone

Return to China Unicom:

Beijing direction: take gtt from Germany to China Unicom AS4837

Shanghai direction: take cogentco to connect with China Unicom as4837

Guangzhou direction: Take Tata from Germany to China Unicom as4837

Return and move to mainland China: they all go from the de-cix data exchange center in Germany to the node in Frankfurt, which is very well optimized

TIKTOK seems to be out of business:

Unix bench Mark：

A rough summary:

On the outbound journey, China Telecom and China Unicom both bypass the United States, while China Mobile is direct;

Return trip,

Telecoms are all through TATA, Telia, and Cogentco. Considering that these are fried to a pulp at night, pity the telecom users;

China Unicom and China Telecom have the same backhaul, but AS4837 is different. China Unicom’s international network is better than China Telecom, which is generally recognized;

Mobile, kill everything directly from the mobile German node
