1.簡單介紹

webbench最多能夠模擬3萬個并發連接去測試server的負載能力。編譯和配置簡單，僅基于TCP協議上對server進行測試。

Webbench也是開放源代碼。從代碼上看，每一個client都fork出一個進程進行測試。僅在TCP協議層對server測試。并未涉及HTTP協議。

2.安裝

源代碼下載:?http://blog.s135.com/soft/linux/webbench/webbench-1.5.tar.gz
tar zxvf webbench-1.5.tar.gz
cd webbench-1.5
make

注：假設安裝過程中出現/bin/sh: ctags: command not found

則需安裝ctags。下載地址：wget http://prdownloads.sourceforge.net/ctags/ctags-5.8.tar.gz

3.測試

1分鐘1000個client測試。執行命令：./webbench -c 1000 -t 60
