V5Net: Simple evaluation of Hong Kong’s 50G high-defense independent server, speed 666

v5net provides high-defense server services in Hong Kong, with up to 50Gbps defense, and is connected to cleaning centers in Asia-Pacific, Europe and the United States, without the need for CDN, etc., to carry it out directly. This evaluation does not involve defense issues. At least there is no attack test traffic here. We simply test this Hong Kong high-defense server as an ordinary server and check some parameters such as the network under normal circumstances to see if Suitable for our use in the Mainland. Data is for reference only!

The test used a dual-channel e5-2630v2, 64G memory, 1T SSD, BBR was turned on, and the approximate hard drive I/O was 339MB/S:

FIO test, this is more detailed in reading and writing the hard disk, take a look:

The official bandwidth is 20Mbps, with no traffic limit; here we use the nodes of speedtest.net + the nodes of the three mainland networks to do a rough test. In the figure below, the uplink bandwidth is basically close to full, and the downlink bandwidth is basically close to full. The bandwidth exceeds 20Mbps, obviously 30Mbps:

The effect during the evening peak period is almost not attenuated, so it seems that the network is still very powerful:

Test results of other nodes in Asia:

The results of running iperf3 in Europe and America are as follows:

Use the browser directly to download files stored on the server to test the bandwidth and network effects:

Evening peak hours can still be full:

PING data for synchronous testing of 80 nodes in mainland China, provided by ping.chinaz.com:

For the outbound journey of China Telecom, take CN2:

China Unicom outbound, direct connection to backbone network:

Move the outbound journey and convert the backbone to CMI:

Return to Mainland China Telecom: The Beijing direction takes the Hong Kong Mobile node and returns to China Mobile and then switches to China Telecom. The Shanghai direction takes the Hong Kong Unicom node to Mainland China Unicom and then switches to China Telecom. The Guangzhou direction uses the Hong Kong Telecom node to directly connect back

Return to Mainland China Unicom: After walking around the KT line in South Korea, return to the mainland

Return, move to the mainland: direct connection back to the mainland

Finally, run Unix bench on a single core to see the effect:

To summarize:

Since it is a Hong Kong high-defense server, and the official website also said that it will connect to Europe, America and Asia-Pacific lines for cleaning, it should be normal to take a detour when being attacked. During the test, we saw that the return trip took South Korea's KT ...But the impact on speed is not big. In short, Hong Kong's defense is really expensive...for completely direct-connected hard defense, the price is sky-high, and you need to have mines at home.
