Server access speed

The access speed of the server must be considered , How to test the server access speed ？ Through different test methods , Include ping value , Open the page , Download these basic indicators to consider . It is also a relatively basic and accurate speed measurement method , And novice Xiaobai can also operate .

One 、 The test method

1.ping command

Website speed is not good , Test whether it is the website problem or the server problem , Will use this command to test . Click start in the computer , function , Then input CMD open DOS Command window . Then enter the website URL , Or the server's IP Address . After using the command , Will feed back a result , This result basically includes the following information .Time, This is the response time , The smaller the time, the better , The response time of domestic servers is generally 30-80ms Between . Packet sending information , There is a packet loss rate , The smaller the value, the better , Normally, the display is lost 0.

2.tracert Command simple speed measurement

Test methods and ping Command similar , It is used to detect from the terminal client to the computer room where your server is located “ Hops ” And response time , That is to test the connection speed between the server and customers everywhere , When you reach a gateway ,directadmin install , There will be three tests , And the results of the three tests are ms Display in units , Of course time The shorter the time, the better .

3. Website speed test tool

Many speed measuring tools can be used , Be able to provide suggestions on the speed of the website , The webmaster can optimize the site according to these suggestions . Then find out the reasons for the slow loading speed one by one .

4. Website loading speed

You can use tools to test the speed of opening websites . The basic working principle is through connection , Show two real web pages in the browser , The result of the reaction is the comparison of the real opening speed of the two websites

Two 、 Test and analysis

1. Test different performance

The services provided by general websites are nothing more than online browsing 、 download 、 Upload, etc , We need to test the above operations on the server , To ensure that the performance of the server under different operations can be comprehensively tested , Record the value of each performance , Multi party comparison .

2. Use different lines

When testing, we should use different circuits to test , Never try to save trouble , Use only one circuit to test , That way, if you use the telecommunication line to access quickly , But you will be miserable if you use Unicom to access the extremely slow server . It is necessary to use different circuits for testing .

3. Test in time

General service providers provide 24 Hours of testing , Never take time to finish the test just in the morning . Because usually a large website every day 24 Customers will visit within hours , If you only test the speed in the morning , And ignore the speed at night , In case the speed of this server is very fast during the day , And if the night is slow , The test is in vain . It will affect the experience of some of your customers . So our approach is 24 In hours 12 Time period , every other 2 Test once every hour , Compare the speed change , If the speed varies greatly , It means that the access of the server is not very stable .
