Simply evaluate spinservers’ high-end servers in Dallas data center and share test data for easy reference.

The latest news from spinservers is that it has added a lot of cabinets in Dallas. Among them, 2*e5-2696 v3, 512G DDR4, 8.4T SSD servers may be available for about 2,000 units... Since spinservers has always provided high configuration and low cost The low-priced American server has a high cost performance, so it is impossible to only test San Jose and ignore Dallas... The webmaster has made a high-end version for everyone to make a simple evaluation. The data is for reference only.

End of promotion below February 15th!

The CPU is e5-2696v3 (2.3GHz frequency), dual-channel, which is 36 cores and 72 threads, and the hard disk I/O is approximately 623MB/S:

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

The server has access to 10Gbps bandwidth (shared) by default, providing 20T traffic, and supports expansion. Let’s see what effect the spinservers network in Dallas computer room can perform in mainland China. Please use speedtest.net’s three network nodes in mainland China for testing. We can roughly see that the uplink in mainland China is less than 500Mbps, and the maximum downlink is 3688Mbps:

For comparative testing, the time period during the evening peak period is compared. Overall, the attenuation is quite obvious:

Test data of nodes in other regions of Asia:

Iperf3 runs roughly in Europe and the United States, with a maximum send of 4.71Gbps and a maximum of 4.09Gbps ​​of received:

The webmaster of the files stored on the server is Guangzhou Telecom. The download speed is measured directly through the Chrome browser. It can reach 12.5MB/S in broad daylight:

It can reach 7.8MB/S during the evening peak. This attenuation is quite obvious. If you compare it, you can see:

Latency data of 80 nodes monitoring IP in mainland China:

Outbound telecommunications, backbone network docking with cogentco:

China Unicom outbound, backbone network docking with GTT:

To move outbound, CMI connects to cogentco:

On the return trip to China Telecom: all via cogentco to connect to the telecom backbone network

Return to China Unicom: Take GTT from Los Angeles or San Jose to connect with China Unicom AS4837 to return home

Return, move to mainland China:

Beijing direction, Los Angeles cogentco docking mobile backbone;

In the direction of Shanghai, return directly from the mobile node in San Jose;

In the Guangzhou direction, due to too many routing tests, it is restricted. The displayed result is 403. The actual routing is OK; 38.19.140.98 is the Los Angeles cogentco node, and 223.118.10.81 is the China Mobile Los Angeles node. We will come back directly later.

For some stress tests on the system, feel free to take a look:

Streaming media test, for reference only:

Roughly evaluate:

On the outbound journey, China Telecom and China Mobile use the backbone network to connect to cogentco, while China Unicom uses the backbone network to connect to GTT;

On the return trip, all cogentcos of China Telecom are connected to the backbone network, and all GTTs of China Unicom are connected to AS4837 and China Mobile (when going to Beijing, the cogentco is connected to the backbone network, and in Shanghai and Guangzhou, the mobile nodes in San Jose or Los Angeles are directly returned to China);

Relatively speaking, it may be more suitable for China Unicom user group. The explosion of China Telecom and China Mobile during the evening peak period will definitely be greatly affected.
