1.簡介
webbench最多可以模擬3萬個併發連接去測試服務器的負載能力，編譯和配置簡單，僅基於TCP協議上對服務器進行測試。Webbench也是開放源碼，從代碼上看，每個客戶端都fork出一個進程進行測試，僅在TCP協議層對服務器測試，並未涉及HTTP協議。
2.安裝
源碼下載: http://blog.s135.com/soft/linux/webbench/webbench-1.5.tar.gz
tar zxvf webbench-1.5.tar.gz
cd webbench-1.5

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個客戶端測試，運行命令：./webbench -c 1000 -t 60
