Simple evaluation of zji one-machine 3-line server, evaluation of Hong Kong Alibaba Cloud dedicated line server

"Zji Hong Kong physical machine: one machine with 3 lines, Alibaba dedicated line + Huawei dedicated line + Kwaiwan direct connection, dual line cn2, 20% off, 800 yuan/E5-2630L/16g memory/1T SSD/10M bandwidth" has been introduced One machine has three IPs, and each IP takes a different route, including the Alibaba Cloud Hong Kong dedicated line and the Huawei Cloud Hong Kong dedicated line, which are the legendary dual CN2 dedicated lines. The webmaster was very curious, so he got a machine and gave everyone a simple test.

In the background of the website, we can see some useful information: IP, resource usage charts, power on and off, system reinstallation, etc.

Here we have a dual-channel e5-2630L machine with 32G memory. The webmaster chose the Alibaba Cloud dedicated line public network IP to log in to SSH. The IP we see displayed is that of Alibaba Cloud Hong Kong. Therefore, this evaluation Based on the Alibaba special line in the third line!

FIO test, pay attention to 4K:

speedtest China node tests the uplink and downlink bandwidth. Since the test machine provides 20M bandwidth, what we see is that the uplink basically runs at 20Mbps, and the downlink can roughly be seen to be 30Mbps:

The webmaster deliberately tested it again during the evening peak period, and we found that there was almost no difference between day and night:

speedtest tests in countries or regions in Asia are basically the same, and the bandwidth results are very good:

iperf3 is running in Europe and the United States, and the effect is still very impressive:

A file was stored on the test machine. The webmaster is Guangzhou Telecom. The direct download effect of the Chrome browser directly fills up the server bandwidth itself:

The effect of Unix bench running on a single core is as follows:

ping.chinaz.com provides ping test data of more than 120 nodes in mainland China. During the test, it was estimated that there was some problem with some test nodes in Tianjin and Beijing. The data was too high, which was obviously unreasonable. The rest were still OK. OK

For the outbound journey from mainland China, China Telecom uses CN2, China Unicom uses the AS9929 high-end VIP route, and China Mobile uses the CMI:

Return to Mainland China Telecom: all are via route 59.43 of CN2

On the return trip to China Unicom: what we saw was the telecom CN2 that China Unicom took to come in

Return to China Mobile: Like China Unicom, we also take the 59.43 segment of China Telecom CN2

To summarize: for the outbound journey, China Telecom and China Unicom use CN2, and China Mobile's own CMI; for the return journey, all three networks use CN2; basically the routing optimization is already very impressive!
