If the workload is large and the system is poorly tuned, it can take a long time to get a baseline performance number.

如果工作负载很大而且系统优化不好，则需要花很长时间才能获得基准性能值。

Before changing anything, it is critical to get a baseline performance number, because only a comparison to the baseline can definitively show that the system is faster or slower.

在进行任何更改之前，获得性能基准数是很重要的，因为只有与基准进行比较才能确切说明系统变快还是变慢。
