Apache AB pressure test tool

The Ab.exe (apachebench) program in the Apache Bin directory is designed for use in stress testing software. Apachebench (AB) is used to test Apache execution efficiency, specifically to perform the performance of the website server, especially for Apache Web server, which was originally used to detect the performance of Apache Web server. In particular, Apache can tell how many pages can be sent per second.

Examples of AB use:
Usage:/usr/sbin/ab [Options] [http[s]://]hostname[:p Ort]/path

AB has a number of parameters, commonly used are:

-N: Total number of requests executed, default is 1;
-C: Concurrency number, default is 1;
-p:post data files;
-W: Outputs the result in the format of an HTML table.

The following is a 100 concurrent 500 accesses to an address at the command line (test results are output to the C-drive test2.html, and each output is cumulative).

C:\apache24\bin>ab-n 500-c 100-w http://127.0.0.1:8080/bpmv8.0/r?wf_num=D_S00

The output of the HTML results is as follows:
