contabo: A simple evaluation of VPS in the "St. Louis" data center in the central United States

contabo's Central United States data center "United States (Central)" is in St. Louis, which is almost the geometric center of the physical location of the United States. This time, we still use the lowest model of VPS (selecting NVMe series hard drives) to do a simple evaluation for everyone. The data is for reference only!

Official website: https://contabo.com/en/

I have recently opened several AMD EPYC 7282 series CPUs. The default choice is the lowest model, with 8G memory, 4 cores, 50G NVMe, 30T traffic/month, 200Mbps bandwidth... I gave BBR as soon as I got the VPS. When it is turned on, the hard disk I/O is approximately 568MB/S:

Refer to FIO, it may be more accurate:

Let’s see how far the network can run in mainland China. I have a rough idea of ​​how far it can go. Speedtest.net’s multi-node test of the three networks in mainland China, let’s first see the effect in broad daylight:

Then let’s take a look at the effect during the evening peak period, which is what everyone calls the explosion of the backbone network:

Roughly speaking, although it is a city in the middle of the United States and has a bandwidth limit of 200Mbps, the actual running effect is not bad during the evening rush hour. It is not bad, right? !

Then take a look at the results of speedtest testing other nodes in Asia:

iperf3 running in Europe and America:

Guangzhou Telecom, let’s use a browser to actually download files on the VPS, and the download rate is 12.3MB/S during leisure time during the day:

Note that compared to the evening peak, 10.5MB/S is only five-sixths of the original:

Let’s take a look at the PING value, the data of 80 nodes in mainland China provided by ping.chinaz.com:

For the outbound telecommunications journey, the backbone network is connected to cogentco, logged in in San Jose, and then transferred to mainland China in the United States:

China Unicom outbound, backbone network connected to HE.NET, Los Angeles login...

Mobile outbound journey, Hong Kong CMI docking cogentco, San Jose login...

Return to China Telecom: In the direction of Beijing, this route is so fucking magical; in the direction of Shanghai, Sheng He Shi Ah Cogentco connects to the telecommunications backbone; in the Guangzhou direction, Salt Lake City Cogentco connects to the telecommunications backbone network

Return to China Unicom: In the direction of Beijing and Guangzhou, exit from Los Angeles level 3 and connect to China Unicom AS4837 to return home; in the Shanghai direction, take San Jose level 3 and connect to AS4837

Return to China Mobile: In the direction of Beijing and Guangzhou, connect to China Mobile AS9808 from Seattle level 3 and return to China; in the direction of Shanghai, return directly from the San Jose mobile node

Then run a Unix bench:

To summarize: at least there are no detours for the three networks in the backhaul. China Telecom uses cogentco to connect to the backbone of China Telecom; China Unicom uses level 3 to connect to China Unicom AS4837, and China Mobile also uses level 3 to connect to AS9808; from a routing perspective, the backhaul between China Unicom and China Mobile is more optimized than China Telecom. It has to be better; it’s hard to say the specific effect, you will know after you try it yourself!
