Simple evaluation of the physical server of the cn2 line of the imidc Russian data center (actually the third-line backhaul cn2)

Caihong Network provides Russian servers, Hong Kong servers, Taiwan servers, and Japanese servers. They are all high-quality high-speed networks with fast access speeds in mainland China, at least that's what the promotion says. The Russian Internet has an advantage. In many cases, there are no DMCA copyright issues, and there is no need for registration and other issues, so it is a relatively popular foreign server gathering place. This time, we will conduct a simple evaluation of Rainbow Network’s Russian server. The data is for reference only. Feedback is welcome!

This test used e3-1230v2, 16G memory, 480G SSD, 30Mbps (cn2+bgp) network configuration, the approximate I/O is 389MB/s:

It’s actually quite good to pass the FIO test:

Speedtest.net’s mainland China node test shows that the uplink bandwidth can basically reach about 27M, and the downlink bandwidth is basically close to full:

speedtest.net's test in Asia, the effect is slightly worse:

The results of iperf3 tests in Europe and the United States are similar to those in mainland China, maybe a little better:

The test file on the server, Guangzhou Telecom, Chrome browser download speed is approximately 2.6MB/S (20.8Mbps):

Unix bench Mark score:

Test data of more than 120 nodes in mainland China provided by ping.chinaz.com, China Telecom and China Unicom are good, but China Mobile is relatively poor:

For the outbound journey, China Telecom takes CN2, China Unicom takes CN2, and China Mobile takes CMI international line:

Return to China Telecom: all via the CN2 network

On the return trip to China Unicom: it is mandatory to take Telecom CN2

On the return trip to China Mobile: Or use Telecom CN2 to return home

To summarize: that is to say, China Telecom and China Unicom use two-way cn2. China Mobile's outbound journey uses CMI and it seems that PING is high, but the return journey uses cn2 network speed. Therefore, in general, the speed of the network will not be exaggerated. , if you like Russian servers, you can consider it immediately!
