篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了使用LoadRunner怎么进行性能测试相关的知识，希望对你有一定的参考价值。
参考技术A 用loadrunner先截取脚本，把对应的变量进行替换，设置成参数表的形式。然后定义对应的用户数，批量的执行脚本，压力测试对应的时间后，loadrunner会自动的分析出对应的性能。同事你需要在数据库服务器和应用服务器上部署对应的性能监测工具用来分析压力测试中服务器的性能。
但建议用jmeter，这个是开源的文档多，loadrunner要钱的。
LoadRunner如何对GIS服务器进行性能测试
1、需求了解
首先确定对gis服务器压测的测试范围，形成具体的测试用例，gis平台都是通过网页端的javascript api调用的gis集群服务接口，通过LR录制上一步中的业务操作，找到javascript向gis服务器请求的地址做参数化后形成压测脚本，实现对GIS服务器的压力测试。
2、测试范围
ARCGIS性能测试主要范围有三个：ARCGIS生成基础地图服务、空间查询服务、为地图提供数据的服务接口的性能,本文主要对ARCGIS生成基础地图服务性能测试进行介绍。
3、测试工具
LoadRunner 11
4、测试步骤
4.1脚本准备
利用loadrunner对地图查询业务进行录制，录制脚本如下：
1 Action() 2 { 3 lr_start_transaction("查询"); 4 5 web_custom_request("0_4", 6 "URL=http://xxx.xx.x.xxx:xxxx/arcgis/rest/services/xxx/{服务名称}/MapServer/0?f=json", 7 "Method=GET", 8 "Resource=0", 9 "Referer=http://xxx.xx.x.xxx:xxxx/xxxgis/aigis/map.html?module=%E4%B8%9A%E5%8A%A1%E5%88%86%E5%B8%83", 10 "Mode=HTML", 11 "EncType=application/x-www-form-urlencoded", 12 EXTRARES, 13 "Url=0?f=json", "Referer=http://xxx.xx.x.xxx:xxxx/xxxgis/aigis/map.html?module=%E4%B8%9A%E5%8A%A1%E5%88%86%E5%B8%83", ENDITEM, 14 LAST);
