raksmart Los Angeles bare metal cloud evaluation data sharing, tell you how raksmart is

The "Bare-Metal Cloud" of the raksmart computer room is called "Bare-Metal Cloud" in English and is distributed in Silicon Valley (San Jose), Los Angeles, Hong Kong, and Tokyo, Japan. The Los Angeles Bare Metal Cloud tested this time is also the last data center tested so far. If you are interested, you can read the evaluation articles of bare metal clouds in other data centers: Hong Kong, Japan, and Silicon Valley. With this article, you can get a general understanding and see which one is suitable for you!

Through the previous test, I learned that the bare metal cloud seems to use the CPU model e5-2697v2, with a main frequency of 2.7GHz and a hard disk I/O of about 225MB/S. I turned on BBR (I don’t know if it is useful, but At least it doesn’t hurt):

The following is the detailed test data of FIO's hard disk read and write:

The default bandwidth of the Los Angeles Bare Metal Cloud is 100Mbps, and it is a mainland-optimized network. We used speedtest.net's three-network nodes in mainland China to test how far the network in mainland China can run. The data is as follows:

Test results in Asia and other nodes within Asia:

iperf3 test results in Europe and the United States:

The webmaster of the files stored on the test machine is Guangzhou Telecom. The download speed directly using the browser is about 7.4MB/S:

Comparatively observe the attenuation effect of the backbone network explosion period during the evening peak:

Pay attention to the delay, the detection data of more than 60 nodes in mainland China on ping.chinaz.com:

Outbound telecommunications, direct connection to backbone network:

China Unicom outbound: direct backbone connection

Mobile outbound, CMI followed by cogentco:

Return to Mainland China Telecom: The return trip to Beijing and Shanghai is CN2, and the return trip to Guangzhou is the cogentco backbone

Return to China Unicom: directly connect from China Telecom’s node in Los Angeles and transfer to China Unicom after returning to China

Return to China Mobile: For Beijing and Guangzhou, take China Mobile's node in Los Angeles and return directly to China; for Shanghai, take China Mobile's node in San Jose directly back to China

Unix bench Mark: Bare metal cloud is not a bare metal server or a stand-alone server. It has castration on CPU performance and is not suitable for running tasks with higher load. Please pay attention to this.

Streaming media unlocking test, for reference only:

To summarize:

For the outbound journey, China Telecom and China Unicom are directly connected. For the outbound journey of China Mobile, CMI is connected to cogentco which is not ideal;

The return trip is basically a direct connection from the three networks' nodes in Los Angeles or San Jose, and China Telecom also has CN2 blessing.

The performance loss on the CPU is too large and is not suitable for high-load services. It is only suitable for some small and medium-sized tasks.
