How about big network data? Let’s test the cloud server with 2Gbps bandwidth

The cloud servers and independent servers of big network data have higher configurations than others when the price is the same, and the price is much cheaper than others when the configuration is the same. They also come with at least 100Gbps high-defense by default, and are very cost-effective during promotions. , many people are eager to try it! Big network data (dwidc) has appeared on us many times, and it has only been officially tested until now. I want to share the data with everyone, hoping to have some reference for those brothers who want to buy big network data.

The webmaster has built a cloud server with 8G memory, 8 cores, and 2Gbps bandwidth. The e5-2690v4 (2.6GHz main frequency) CPU is not bad. Everyone is familiar with AS4134. The current hard disk I/O is roughly 545MB/S. looks like:

FIO tests hard disk reading and writing data:

Test it with DD, approximate data:

Another Unix bench killer, the performance is not bad, right? :

Let’s take a look at the delay first. Mainland China’s seems a bit unnecessary?

Routing? Forget it, can machines from mainland China go abroad by detour? Ignore the unexpected!

Next, what we focus on is bandwidth. How much it can run is the key!

Drag the file on our chick on the VPS node of Hong Kong CMI line, the speed is as follows:

It’s so boring to use foreign nodes to test machines in mainland China:

Let’s take a look at the multi-nodes of speedtest.net in the three networks in mainland China. Let’s run it and see how far the uplink and downlink can reach, right? 2Gbps bandwidth, many upstream exceed 1900Mbps:

Same as the above nodes, we change the evening peak time period to test, some nodes can reach 1949.4Mbps:

The webmaster’s Guangzhou Telecom home bandwidth is only 100Mbps. Let’s use a browser to download the files stored on the test chicken and see how fast the download is. It’s probably close to full capacity:

There is no change in download speed during the evening peak:

Continue to look at Sichuan Meishan Unicom. A 500Mbps bandwidth machine pulls this file with a 2Gbps bandwidth. The speed is 57.9MB/S, which is almost close to the bandwidth of Meishan Unicom:

Similarly, let’s look at the evening peak period. This Meishan machine enlarges files on the cloud server. The speed is roughly 58.7MB/S, which is basically a slow bandwidth:

The webmaster's resources are limited, so he launched a mass line below, and the network in the QQ group helped download the speed test:

This guy from Sichuan Telecom reached 103.35MB/S, which is too brutal:

Yunnan Mobile seems to be talking about 500M bandwidth, which can run 39.46MB/S. It is said that there are fluctuations:

Morgan’s Changsha Telecom 500M bandwidth can run 50.2MB/s:

Zhejiang Shaoxing China Unicom, download speed is approximately 17MB/S:

Zhengzhou Unicom’s download speed: 59.4MB/S:

There seems to be nothing to test on machines in mainland China. It mainly depends on whether the network is sufficient. Dawang Data officially revealed that as long as the customer's budget is sufficient, they can provide a single machine with 40Gbps exclusive bandwidth (of course, this machine has a relatively high configuration, which is also quite expensive).
