某软件公司为某银行设计开发了一套网上银行系统,该系统提供基本的支付、查询、转账和信息修改等功能。银行对网上银行系统提出了初步的性能指标:
4交易响应时间不超过2s
5并发用户数>=1000
6CPU利用率不超过80%
7系统需要7*24小时不间断的稳定运行
8每秒事务数为7
9交易成功率为100%
现需要对该软件进行性能测试。
在测试性能指标(5)时,该软件公司在客户端模拟大量并发用户来执行业务操作,统计平均的每秒事务数。该软件公司认为客户端接收响应信息与该性能指标的测试无关,因此在模拟客户端上发起正常业务申请,接收系统响应后直接丢弃响应信息,没有进行功能校验。请说明该软件公司的做法正确与否,并简要说明原因以及执行功能校验的副作用。
