You can change a parameter, a line of code, or a workload item, and rerun your benchmark to get a good measurement of the impact of the change.
您还可以改变参数，某行代码，或者工作负载项，甚至可以重新运行基准测试以获得好的度量结果。

Item response theory is considered as one of the best hypothesis to detect the DIF compared with the classical measurement theory.
与经典测量理论相比，在测查项目功能差异时，运用项目反应理论有较强的前提假设和优越性。
