Simple evaluation of "ceraus" cloud server for Los Angeles large broadband high-quality routes

In addition to the Cera computer room, ceraus's American cloud servers also include the Enzu computer room, which is officially named "Los Angeles Big Broadband Premium Route". It has a special offer at the end of the year, providing ultra-high configurations with 50 or 100M bandwidth and unlimited traffic, and the price is as low as 199 Yuan. This time we will do a simple test to see how this series of cloud servers perform? !

190 yuan/month, 16G memory, 8 cores, 100G hard drive, unlimited 50M bandwidth

290 yuan/month, 32G memory, 16 cores, 200G hard drive, unlimited 100M bandwidth

This test uses this 290 yuan model with 32G memory and 16 cores; the hard disk read and write is approximately 225MB/S, and BBR is turned on:

Test the hard disk read and write and look at the detailed data of FIO:

In order to test the network conditions of the cloud server, we used speedtest.net to run uplink and downlink directly on the painful nodes of the three networks in mainland China to see how far it ran. The evening peak situation is as follows:

The effect of leisure time during the day is as follows:

Is there almost no difference between the evening rush hour and the daytime rush hour? We'll wait and see how the route goes before we make a judgment!

speedtest node test in Asia, excluding mainland China:

The effect of iperf3 test running in Europe and the United States:

For files stored on the test cloud server, the download speed directly using Chrome during the evening peak hours of Guangzhou Telecom is as follows:

If you are concerned about latency, you can look at the data provided by ping.chinaz.com:

On the way to Telecom, we took CN2:

China Unicom outbound, direct backbone network:

Mobile outbound, direct after CMI:

Return to China Telecom: Telecom’s Los Angeles node connects to CN2 and returns directly to China

Return to China Unicom: Exit the Los Angeles Unicom node and return directly to China via AS4837

Return to mobile in mainland China: leave the mobile node in Los Angeles and connect directly back to China

Run a streaming media test script to see:

Finally throw in a Unix bench, the scores are as follows:

A rough summary:

Telecom uses a two-way cn2; China Unicom and China Mobile are directly connected to the backbone, and the return trip is directly connected to their own nodes on the West Coast of the United States; so the official saying that Los Angeles is optimizing the line is not an exaggeration! When we tested the upload and download tests during the evening rush hour and during the day, there was almost no difference. Overall, the network was indeed quite good!
