linux下開啟ab的man頁面，介紹如下：
NAME ab - Apache HTTP server benchmarking tool SYNOPSIS ab [ -A auth-username:password ] [ -b windowsize ] [ -c concurrency ] [ -C cookie-name=value ] [ -d ] [ -e csv-file ] [ -f protocol ] [ -g gnuplot-file ] [ -h ] [ -H custom-header ] [ -i ] [ -k ] [ -n requests ] [ -p POST-file ] [ -P proxy-auth-username:password ] [ -q ] [ -r ] [ -s ] [ -S ] [ -t timelimit ] [ -T content-type ] [ -u PUT-file ] [ -v ver? bosity] [ -V ] [ -w ] [ -x <table>-attributes ] [ -X proxy[:port] ] [ -y <tr>-attributes ] [ -z <td>-attributes ] [ -Z ciphersuite ] [http[s]://]hostname[:port]/path SUMMARY ab is a tool for benchmarking your Apache Hypertext Transfer Protocol (HTTP) server. It is designed to give you an impression of how your current Apache installation performs. This especially shows you how many requests per second your Apache installation is capable of serving.
每個引數的介紹，網上已經有很多了，比較實用使用的2個引數是
-c 併發連線數
-n 請求總數
Options are:
-n requests Number of requests to perform
-c concurrency Number of multiple requests to make以下是使用ab對淘寶的nginx伺服器（tengine）進行測試的結果：
