系统响应时间和作业吞吐量是衡量计算机系统性能的重要指标。对于一个持续处理业务的系统而言，其（ ）。
- A.响应时间越短，作业吞吐量越小
- B.响应时间越短，作业吞吐量越大
- C.响应时间越长，作业吞吐量越大
- D.响应时间不会影响作业吞吐量
正确答案及解析
正确答案
解析
系统响应时间是指用户发出完整请求到系统完成任务给出响应的时间间隔。作业吞吐量是指单位时间内系统完成的任务量。若一个给定系统持续地收到用户提交的任务请求，则系统的响应时间将对作业吞吐量造成一定影响。若每个任务的响应时间越短，则系统的空闲资源越多，整个系统在单位时间内完成的任务量将越大；反之，若响应时间越长，则系统的空闲资源越少，整个系统在单位时间内完成的任务量将越小。
