Cloudsilk's Hong Kong vps evaluation, forcing the three networks to use mobile CMI lines for return

The Hong Kong vps launched by cloudsilk the day before yesterday is connected to the mobile CMI and BGP networks. Internationally, it uses BGP. When returning to mainland China, it is mandatory for all three networks to use CMI lines. The price of mobile direct-connected VPS is not bad. Relatively speaking, it should be relatively popular among Hong Kong VPS. Therefore, here is a simple evaluation for everyone. The data is shared as follows for reference only!

I got the lowest configuration VPS with a main frequency of 2.1GHz and a hard drive I/O of about 360MB/S. I turned on BBR:

FIO tests hard disk read and write, the data is more detailed, as follows:

Whether the VPS is effective in terms of speed or not, the core is how much bandwidth can be used in the mainland. Here we use speedtest.net's three network nodes in mainland China to do a simple test. Everyone focuses on upload speed:

The following is tested during the evening peak period. Let’s compare the data tested during the day:

The test speeds of other nodes in Asia are as follows:

The results of iperf3 testing European and American nodes are as follows:

The files stored on the test VPS have Guangzhou Telecom 200M bandwidth (25% redundant bandwidth) and a download speed of 28.9MB/S. This effect is quite impressive. I used WiFi for testing!

The speeds tested during the evening peak period are as follows, compared with those during the day:

80 nodes in mainland China (mainland) are used to test the delay, roughly as follows:

On the outbound telecommunications journey, the backbone network connected to NTT bypassed Japan and returned to Hong Kong:

On the outbound journey of China Unicom, the backbone network connected to NTT bypassed Japan and returned to Hong Kong:

Mobile outbound, CMI direct connection:

Return to Mainland China Telecom: all use AS9808 Mobile CMI and then transfer to China Telecom

Return to China Unicom: Mobile CMI and then transfer to China Unicom

Return to mainland China: direct connection after mobile CMI

Let’s take a look at some simple performance tests:

Unix bench Mark：

Finally, let’s take a look at the streaming media unlocking test:

A rough summary:

Although China Telecom and China Unicom use NTT to bypass Japan, China Mobile uses CMI direct connection;

However, as the return trip is forced to use CMI direct connection, this makes up for the speed experience of mainland users;

The large bandwidth of 500Mbps should be trivial for building a website or watching videos.
