raksmart: A simple evaluation of the "Mainland Optimized Line" server in the Korean data center

raksmart’s Korean servers are divided into Korean premium network servers and Korean mainland optimized servers. They are two different lines. We have previously written an evaluation article on “Boutique Network”: “raksmart: Korean computer room “independent server” evaluation, sharing the actual test network The effect, tell you how the raksmart server is." This time I will evaluate the mainland optimization route for everyone. The data is for reference only. Those who want to buy Korean servers can take a closer look!

Tested server configuration: dual-channel e5-2630L, 32G memory, 400G SSD (but usually given randomly, may be larger than 400G), 30Mbps bandwidth (optimized in mainland China), BBR is enabled by default, hard disk I/O is approximately 213MB /S，

Judging from the FIO test, it’s still OK:

To know how much bandwidth the server can run in mainland China, we first use the mainland China node of speedtest.net to test the uplink bandwidth and downlink bandwidth. The script test shows that the uplink is basically up to standard, but the downlink bandwidth seems to be close to 1Gbps. (This is not officially guaranteed. It would be reasonable if it was adjusted to 30Mbps later):

Speedtest’s Asian regional nodes, excluding Chinese nodes, the test results are as follows:

iperf3, when running in Europe and America, the effect also meets the bandwidth label of 30Mbps:

Webmaster Guangzhou Telecom, Chrome directly downloaded the files on the test server. At the evening peak time of 7:58, the download speed reached 2.9MB/S:

I ran a Unix bench and the single-core score was 958. It is probably an error in the test script. The multi-core was disconnected before it finished running. Let’s leave it like this:

Many people pay attention to the PING value. The test data of more than 80 nodes in mainland China provided by ping.chinaz.com:

Judging from the ping situation, it is actually pretty good:

The outbound route of China Telecom is via CN2:

China Unicom, backbone directly connected to South Korea's LG:

Mobile outbound journey, direct from Hong Kong CMI to South Korea:

Return to Mainland China Telecom: All are CN2

Return to China Unicom: also use the CN2 link to return home

Return to China Mobile: Borrow China Telecom’s CN2 link to return home

If you come to mainland China, just try AS9929 and CN2:

To summarize: China Telecom uses CN2, China Unicom direct connection, and China Mobile CMI for the outbound journey, and all three networks use CN2 for the return journey. The effect should be quite reliable.
