"Performance Test Tool"-webbench

Advantage: Simulation of concurrency is greater; disadvantage: statistical results are limited

Overview:

Webbench, developed by Lionbridge Inc. (http://www.lionbridge.com), is a Web site stress testing tool under Linux that emulates up to 30,000 concurrent connections to test the load capacity of a Web site. Using the fork () function to generate a certain number of concurrent requests, the supported request protocols include http/0.9----http/1.1 ("HTTP 0.9/1.0/1.1" http://www.cnblogs.com/musicmovie/p/ 3892648.html). The results returned include pages/min and Bytes/sec, which represent the corresponding requests per minute and the amount of data transferred per second. Webbench not only has the ability to test static pages, but also has the ability to test dynamic pages (asp,php,java,cgi). Also, it supports static or dynamic performance testing of secure websites that contain SSL, such as e-commerce sites. Note: Webbench When doing stress tests, the software itself consumes CPU and memory resources, in order to test the accuracy, please Webbench installed on a different server.

Installation:
Tar zxvf webbench-1.5.tar.gz
CD webbench-1.5
Make && make install

Basic use:

Example 1

xxxxxxxxxxxxxxxx$ webbench-c 10-t 5 http://www.douban.com//* Concurrency number is 10, execution time is 5 seconds */

Webbench-simpleweb Benchmark 1.5

Copyright (c) radimkolar 1997-2004, GPL Open Source software.

Benchmarking:get http://www.douban.com/

Ten clients, Running5 sec.

Result of Instance 1

Speed= 31152pages/min, 158051bytes/sec. /* Number of response requests per minute: 31152pages/min, data transfer per second 158051 bytes/sec.*/

requests:2596 susceed,0 failed.

Example 2

xxxxxxxxxxxxxxxx$ webbench-c 10-t 5-f http://www.douban.com//* More than ' instance 1 ' with an-f parameter, indicating unequal server response */

Webbench-simpleweb Benchmark 1.5

Clients, Running5 sec, early socket close.

Result of Instance 2

Speed=63144pages/min, 0 bytes/sec. /* After using the-f parameter, the number of requests sent is significantly greater, but only if the server is strong enough.

Requests:5262susceed, 0 failed. /* No fail request */

discussion / Questions:

• How can I convert my test results to TPS?
• What is the relationship between speed and request in the test results?
