A Simple Method for Testing Data Center speed and bandwidth

So how can we test the data center speed and bandwidth? I believe many people will encounter this problem when choosing a service provider. I hope to help you with the following summary based on your experience!
Let's take a look at how to correctly test the speed of a data center.
The first method is also the most common method, Ping Value
The target IP address or domain name can be used.
Choose Start> RUN> cmd> Ping www.xxx.com-T on the DOS page ". Note that if there is no-T, only four Ping values are not representative. The-t parameter is used to allow ping to continue, knowing that you manually ctrl c to stop.
For a data center with good speed, the packet loss rate should not exceed 1% first, preferably 1000 Ping without a packet loss. This is the most ideal, but this is not the absolute value, as long as less than 1% of the routes are good. Secondly, the ping value is small. The average Ping Value of China Telecom ADSL cannot exceed 20, which is generally 10. The average Ping value of cross-province ADSL is between 20 and 40. The third point is that the ping value should be even. Here we can refer to the moving Ping value results. Although the minimum ping value is only 4, there are dozens from time to time, and the maximum Ping value is 79, this is the result of unstable routing.
The second method to test the route tracert Router
This is to see how many routers need to pass through the test point to the target server, and you can see that the delay is on that router according to the number of milliseconds of each route, you can use the IP NSLookup to check which operator the IP belongs to, or even the operators in that province and city.
The third method is File Download for common users.
This is very simple. First of all, understand the maximum value of your Internet access method. If it is 2 Mbps ADSL, the theoretical maximum download speed is 2*1024/8 = 256kb, the actual maximum download speed is more than kb. If the download speed is kps adsl, the peak value is generally 50-60 kb.
During the test, find the file to be downloaded for more than 50 MB. It takes a little longer. You can download it in a single thread, mainly by taking an average value. If you can reach the download peak in the Internet mode, and it is stable in a numerical segment.
In fact, if you select a regular IDC operator, you should not only look at the speed of the IDC, but also the test results, and immediately cooperate. I personally think that the operator or the customer is good, what does it rely on? It depends on services. It treats each other in good faith and cooperates with each other from the perspective of each other to achieve fair, reasonable, and professional services, what I want is long-term cooperation.
I don't know how to test how to select a regular IDC company! Will it work? However, I think the business representatives in a formal company are honest. After a long time in this industry, I feel like everything is the same. If you treat it with sincerity, you may get a lot of feedback, because such an industry will make you realize many people and many friends.
