Performance test Tool Curl-loader two---test analysis

This article is based on the first article, if you have not installed the Curl-loader Performance testing tool. Please refer to the Performance Test tool Curl-loader (Linux) First

This section specifically analyzes the use of Curl-loader, as well as the meaning of the parameters.

Simple performance testing and requirements environment:

------- -------------------------------------------------------------------------------------------------------- ------- ----------------------

Visit Baidu Home: http://www.baidu.com/index.html

Number of virtual users: 20

Initial start User: 1

Start per Second: 1 (20 seconds after 20 users start all)

Network environment: Local Linux-----extranet Baidu Homepage Bandwidth: 45kb/s (unstable)

Performance Tools: Curl-loader

--------------------------------------- ------------------------------------------------------------------------ -------------------------------

Performance file configuration:

You can find a configuration file in the curl-loader-0.56/conf-examples/directory, the duplicate name is: baidu.conf

[Root@youname conf-examples]# VI baidu.conf Open configuration file for modification

########### URL section ####################################

#URL =http://localhost/ace-install.html        
url_short_name= "Local-index"
Request_type=get    
timer_url_completion = 5000      # in msec. When positive, now it's enforced by cancelling URL fetch on timeout 

   
timer_after_url_sleep =20

As for the meaning of each parameter, the above code has been annotated. After the modification is complete, save the exit!

To run a performance test:

Execute the following command to run the configuration file and start the test.

[root@youname curl-loader-0.56]#  curl-loader  -f  ./conf-examples/baidu.conf       & nbsp     Start running the file you just configured
