How about digital-vm Singapore VPS? Evaluation of Singapore VPS with 10Gbps bandwidth: China Unicom and China Mobile can fly

digital-vm has deployed a VPS business in Singapore, with 10Gbps high-bandwidth access by default. Since Singapore is geographically close to China, many people expect that high-bandwidth Singapore vps should have good results. How about digital-vm Singapore vps? Is digital-vm Singapore vps suitable for the environment of the three networks in mainland China? How is the speed of coming to mainland China? Let’s take a look at our actual measured data, which is for reference only.

The CPU model is unknown, the main frequency is 2.2GHz, BBR is enabled, the ASN is from datacamp, the location is Singapore, and the current hard disk I/O is approximately 411MB/S:

FIO read and write data test, the approximate results are as follows:

Test uplink and downlink on multiple nodes of the three networks in mainland China to see how much it can run, right? It's roughly as follows:

Continue to look at the uplink and downlink tests during the evening peak period:

Test data of some nodes in speedtest Asia region:

iperf3 tests the data of several European and American nodes:

Files stored on the test VPS, Guangzhou Unicom home network, downloaded directly from the browser, approximate speed:

In the evening rush hour, continue to check the download speed:

Evening peak, Sichuan Meishan China Unicom, download speed:

Evening peak, Hubei Shiyan Telecom, download speed:

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

Outbound telecommunications: backbone network docking with NTT first goes to Japan and then from Hong Kong to Singapore

China Unicom's outbound journey: backbone network docking with NTT first goes to Japan and then from Hong Kong to Singapore

Mobile outbound journey: Directly connect to Mobile San Jose node in the United States, then take twelve99 and transfer to PCCW to Singapore

Telecom return:

Beijing direction: take PCCW to Los Angeles, USA and then return to China

Shanghai direction: Shanghai/Guangzhou direction: take Cogent to Germany, and return home from Telecom and Cogent's peer in Frankfurt

Guangzhou Telecom: Go to Germany via cogent and return home from Frankfurt

China Unicom return trip: take NTT to Japan and then back to China

Mobile return trip: Take Singapore NTT to Hong Kong NTT and transfer to Hong Kong CMI back to the mainland

VPS performance test, the data is relatively weak:

A rough summary:

Currently, the CPU performance is weak, the hard disk I/O is not bad, and running projects such as websites is not a big problem;

In terms of network, the telecom return trip either goes around the United States or Germany. China Unicom uses pure NTT to go to Japan and then returns to China. China Mobile uses NTT to go directly to Hong Kong and then connect to the mainland from CMI. To put it simply, the telecom effect is rubbish. China Unicom and China Mobile The effect is quite good!
