用AB对Webservice做压力测试

AB工具下载

AB工具介绍见 web压力测试工具

下载ab工具后放到任意目录下，从命令行打开ab.exe

使用以下命令测试Webservice

ab -c 100 -n 1000 -p zip.txt -v 10 -T text/xml;charset=utf-8 http://localhost/myWebservice/zipcode.asmx?op=call

注：-c 并发请求数量  -n 本次测试总共请求数量  -v 打印出请求和返回信息的级别   -T xml格式的包需特别说明   -p Soap请求的Body部分文件存储路径

其中 zip.txt为webservice请求的包体，格式如：

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <ns2:call xmlns:ns2="http://entry.ws.css.com/">
      <arg0>湖北省武汉市东湖高新区</arg0>
    </ns2:call>
  </soap:Body>
</soap:Envelope>

运行会得到并发测试结果：
