Performance testing tool curl-loader 2-Test Analysis

 

Based on the first article, this article explains if you have not installed the curl-loader performance testing tool. Please refer to Performance Testing Tool curl-loader (Linux) first

This section analyzes the usage of curl-loader and the meanings of parameters.

Simple performance testing and requirements Environment:

Certificate --------------------------------------------------------------------------------------------------------------------------------------------

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

Number of virtual users: 20

Initial User: 1

Start every second: 1 (all 20 users started after 20 seconds)

Network Environment: local Linux ----- Internet Baidu homepage bandwidth: 45kb/s (unstable)

Performance tool: curl-loader

Certificate ----------------------------------------------------------------------------------------------------------------------------------------------

Performance File Configuration:

You canCurl-loader-0.56/Find a configuration file in the conf-examples/directory and copy the file with the name "Baidu. conf ".

 [Root @ youname conf-Examples] #VIBaidu. confOpen the configuration file and modify it.

 

 ########### General section ########################### ##### 
Batch_name = Baidu //  Name of the test object  
 Clients_num_max = 20 //  Maximum number of virtual users  
 Clients_num_start = 1//  Number of users started at the beginning  
 Clients_rampup_inc = 1 //  Start several users every second  
 Interface = eth0 //  Used Nic eth0  
 Netmask = 16 //  Subnet Mask count  
 Ip_addr_min = 192.168.1.1 //  Start IP Address  
 Ip_addr_max = 192.168.53.255 # actually- This Is For Self-control //  Last IP address range  
 Cycles_num =-1 //  -1 indicates an infinite loop  
 Urls_num = 1

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

Url = http://Www.baidu.com/index.html//URL to be tested
# Url = http://Localhost/ACE-INSTALL.html
Url_short_name = "Local-index" 
 REQUEST_TYPE = get 
 Timer_url_completion = 5000 # In msec. When positive, now it is enforced by canceling URL fetch on timeout 
 Timer_after_url_sleep = 20
