They also provided a heuristic with the worst-case performance ratio of 5/3, and this bound is tight.

他们也给出了一个启发式算法，它的最差执行比为5／3，并且这个界是紧的。

Analysis team: Work with the users to capture the key use cases that drive the worst-case performance conditions, such as the peak data load or most critical control scenario.

分析团队：与用户一起工作，捕捉产生最差性能的关键用例的情况，比如数据量峰值或者最关键的控制画面。

Tune for the worst-case load, so that when you go into production, you will already have performance numbers for higher loads.

优化最差情况下的负载，这样您在投入生产时就已经拥有更高负载下的性能值。

This can be considered effectively a worst case scenario, as the couple retired just one year after the worst 10-year stock market performance in American history, from 1999 to 2008.
