At present, the rapid development of domestic IDC market, all kinds of virtual IDC operators have sprung up, regardless of the large small IDC boast their bandwidth how good, how fast, in fact, there are many misunderstandings.
Let's take a look at how to properly test the speed of a room.
The first option is also the best way to ping the value:
Target IP, or domain name can be, for example www.tom000.cn 203.171.230.9
Start Menu-> run-> enter cmd-> enter "ping 203.171.230.9-t" or "ping-t" in the DOS interface
Note that if you do not have-t then the ping value is only 4 unrepresentative, the-t argument is to keep the ping continuing until you manually ctrl C stop.
First try to use Telecom or Netcom ADSL to test, because this is the most representative, and railcom, mobile, long wide broadband due to various interconnection reasons ping value is certainly inaccurate or no way to judge the data, but can be used as a reference basis.
A good speed room, the first packet loss can not exceed 1%, preferably 1000 ping did not lose a packet, this is the most ideal, but this is not absolute value, as long as less than 1% of all belong to a good routing situation.
Second ping value to small, the same city Telecom ADSL ping average can not exceed 40, generally in 10-20, across the province of the ADSL ping average should be in 40-60 normal.
The 3rd is to ping the value evenly, this we can see the result of the ping value of the move, although the smallest ping value is only 4, but sometimes dozens of, the largest 79 of the appearance, this is the performance of routing instability, the same telecommunications adsl, although the smallest also has 8, but the largest also only 9, It shows that Telecom's ADSL routing is better.
Test the second approach, test routing tracert router
This is to see the test point to the target server to go through the number of routers, and can be based on the number of each route through the millisecond to see the router, and through the IP nslookup to see the IP belongs to the operator, or even the operators of that province, so at a glance.
From the test results can be seen, to the target room hops jump number is the better, in the domestic generally around 15-18 for good, with the city should be around 12-15, if the number of individual hops, the number of milliseconds is particularly large, can go to Whois.sc query IP ownership, you can basically determine the slow in the operator there, but 8630.html "> sometimes know that there is no way to slow, China's national conditions are interconnected, so according to your customer base network location to choose Telecom or Netcom is the most important."
The third method, and also the general human file download
This is very simple, first of all know your Internet way maximum, if it is 2MBPS ADSL, then the theoretical maximum download speed is 2*1024/8=256kb, the actual maximum download speed is 200KB or more stable, if it is 512KPS ADSL, It usually peaks at 50-60kb.
Test time to find more than 50M file download, a little longer, with a single thread download, mainly to see an average can be, if you can reach the peak download mode, and stability in a numerical segment, then it can be said to be stable.
The fourth method, but also the most inaccurate, but the most direct, open the speed of the Web page, but there is no good introduction.
