kvmla: Simple evaluation of Japanese Softbank Line VPS, 10M bandwidth, supports Windows

kvmla is an old brand merchant in mainland China (2011~). Recently, I got a VPS from Japan’s Softbank line. I specially conducted a simple evaluation of the VPS. Now I will share the data with you. According to the description on the official website, VPS is based on KVM virtualization, 10Mbps bandwidth (for actual conditions, please see the real bandwidth tested by me), a mixture of SoftBank, ntt, kddi, cn2, and iij lines, supports Eucommia operating systems including windows, and does not provide IPv6 , it is strictly prohibited to do illegal business (if found, you will be killed immediately).

KVM virtual, 10,000 to SAS (raid10), comes with an IPv4, supports Chinese and English versions of Windows + Linux, mixed Softbank, ntt, kddi, cn2, iij lines

The test used a VPS with 2G memory, 2 cores, and 30G hard drive. BBR was turned on, and the average I/O was 314MB:

FIO test:

When testing the uplink bandwidth and downlink bandwidth of VPS with multiple nodes in mainland China, the mobile uplink reached a maximum of 77Mbps and the downlink reached a maximum of 89Mbps. This at least indicates that the bandwidth may be 100Mbps, not 10Mbps as written on the official website:

The picture above is the evening peak test, and the picture below is the test results during the day and leisure time:

The same is true for iperf3 when running in Europe and the United States. The bandwidth should be 100Mbps:

Guangzhou Telecom, according to the actual test, the download speed of the test file on the VPS can reach about 2.3MB/s:

Packet collection effect:

Average data of more than 120 nodes in mainland China provided by ping.chinaz.com:

On the outbound journey of Telecom, the backbone network is connected to SoftBank, and finally to the INAP computer room in Tokyo:

On the outbound journey from China Unicom, the backbone network connects to SoftBank, and finally to the inap computer room:

On the outbound journey, the backbone of Wannian took the CMI export in Hong Kong and transferred it to Softbank to the Japanese computer room:

Return to China Telecom: It seems that the route is hidden, but according to the ping data, it cannot be seen that there is no detour in 70 milliseconds

Return to China Unicom:

(1) In the direction of Beijing and Shanghai, SoftBank is right out of the computer room and connected to China Unicom AS4837

(2) In the direction of Guangzhou, NTT is right out of the computer room and connected to China Unicom AS4837

Return to China Mobile:

(1) The return trip from Beijing is SoftBank, (2) the return trip from Shanghai is KDDI, (3) the direction from Guangzhou is NTT

Judging from the return data, it is not pure SoftBank, but a BGP composed of SoftBank mixed with NTT\KDDI. Maybe there will be more cn2 and iij lines next time you test. This is not surprising. Got it!
