Although different access paths for the same SQL statement produce the same result set, they most likely do not perform the task with the same level of performance.
虽然相同sql语句的不同访问路径会产生相同的结果集,但是它们很有可能不会通过同样的性能级别来执行任务。
The experiment found that though there was no difference in performance - the tasks were very easy - the level of activity in the subjects' brains differed, suggesting different levels of effort.
这项实验发现,尽管表现没有区别——任务相当简单——被研究对象脑部的活动级别不同,显示了努力程度不同。
Similarly, in DB2 z/OS, there are different types of traces that will run at sub-system level to collect information that you normally require for monitoring and performance tuning.
类似地,在DB2z/OS 中,会在子系统级运行不同类型的跟踪,以收集监控和性能调优通常所需的信息。
