FIO tests hard disk read and write data:

Look at data reading and writing again:

The default bandwidth is 50Mbps. Let’s use speedtest to run it on different nodes of the three networks in mainland China to see how much the uplink and downlink bandwidth can reach, right? The approximate test data is as follows:

Looking at the evening peak situation, it seems that the data does not change much:

The test results of some international nodes of speedtest:

Test data of speedtest nodes in Asia:

iperf3 tests the data of several European and American nodes:

iperf3, test several European and American nodes in IPv6 environment:

Guangzhou Telecom downloads the files stored on the test chicken directly using the browser. Let’s check the download speed:

Same as the above test, we focus on the effect of the backbone network blocking period during the evening peak:

Evening peak, Sichuan Meishan China Unicom, download speed:

At evening peak, Hubei Shiyan Telecom, the download speed is roughly as follows:

Latency test data of multi-nodes of three networks in mainland China:

Telecom outbound journey: Directly connect to Telecom and pass through the San Jose node, then take the cogent exit from the east coast of the United States to the United Kingdom and then to South Africa

China Unicom outbound journey: Directly connected to the China Unicom node in Frankfurt, Germany, then take twelve99 through France and the United Kingdom and then transfer to seacomnet to Africa

VPS performance test, some test data:

A rough summary:

The current performance of VPS is okay, but it may be a bit annoying due to the limitation of hard disk I/O;

As for the Internet, both the outbound and return journeys are basically routed around Europe and the United States. Only a few places in China Telecom are directly connected back to China... Generally speaking, it is a VPS with relatively long detours.
