Webbench can simulate up to 30,000 concurrent connections to test the load capacity of the website. I personally feel that it is better than the ab stress test tool that comes with Apache, and it is particularly convenient to install and use.
1. Installation Tutorial
1.1 Installation depends on exuberant-ctags
sudo apt-get install exuberant-ctags
1.2 Download the source code and install
wget http://blog.s135.com/soft/linux/webbench/webbench-1.5.tar.gz
tar zxvf webbench-1.5.tar.gz
cd webbench-1.5
make && sudo make install
Note: If you are prompted to make cc command not found, you need to install the c/c++ compilation environment linux
sudo apt-get install build-essential
1.3 Frequently used methods and instructions
webbench -c 500 -t 30 http://127.0.0.1:3006/
参数说明：-c表示并发数，-t表示时间(秒)
Note: http://127.0.0.1:3006/ is a website written by me.
It can also be tested on Baidu:
so many failures may be due to Baidu's ip monitoring. After all, big companies, well, actually I don’t knew!
1.4 Running webbench will output instruction usage
webbench [option]... URL
-f|--force Don't wait for reply from server.
-r|--reload Send reload request - Pragma: no-cache.

-p|--proxy <server:port> Use proxy server for request.
-c|--clients <n> Run <n> HTTP clients at once. Default one.
-9|--http09 Use HTTP/0.9 style requests.

--trace Use TRACE request method.
-?|-h|--help This information.
-V|--version Display program version.
1.5 Principle
Webbench first forks out multiple sub-processes, and each sub-process loops for web access testing. The child process informs the parent process of the access result through the pipe, and the parent process makes the final statistical result.
