Simple evaluation of V5.net Korean cn2+bgp line server

v5.net operates independent servers and has a branch in the Seoul data center in South Korea. By default, it is connected to China Telecom CN2 and South Korea's KT/LG/HE/SK as the upper-level operators, covering mainland China, Asia Pacific/Europe and the United States. There are special network optimizations! So what is the Korean server of v5.net like? Let us make a simple evaluation for everyone. The existing data is shared below for reference only!

What we are getting this time is a dual-channel e5-2620, 32G memory, 240G SSD, 10M bandwidth server; judging from the data, the IP is broadcast, and the current hardness I/O is at 403MB/S:

FIO tests the reading and writing data of the hard disk in detail:

Let’s test how much uplink and downlink the three network multi-nodes in mainland China can run:

The same test is run again during the evening rush hour:

Some node tests in different regions around the world:

Multi-node testing in Asia:

iperf3 tests European and American nodes:

Files stored on the test server, Guangzhou Telecom, download directly, check the speed:

During the evening peak period, when the backbone network explodes, look at the download speed:

Latency test of multiple nodes of three networks in mainland China:

For the outbound journey of China Telecom, take CN2:

China Unicom outbound, backbone network docking with South Korea's LG:

Move outbound and take CMI direct:

Return to China Telecom: all take CN2

Return to China Unicom: come out of the computer room and connect directly to China Unicom AS4837

Return to China Mobile: directly connect back from China Mobile's Seoul node in South Korea

TIKTOK streaming media unlock test: NO

Cross-regional streaming platform unlocking test results:

It doesn’t make much sense to run another Unix bench. After all, it is an exclusive resource, so let’s run it:

To summarize:

Telecom uses CN2 for round trip, China Unicom and China Mobile are both direct connections for both ways; the network is quite reliable, the physical distance is close, and the price is not expensive; the payment is convenient, and it can be used instead of the registration machine in mainland China.
