基准：有首次测试中，我先确定基准评测的方法。
Baseline: in the first test I sought to obtain a baseline measurement.
开发人员在以编写高性能代码为目标的时候，常常会编写小的基准程序来度量一种方法相对于另一种方法的性能。
Toward the end of writing high-performance code, developers often write small benchmark programs to measure the relative performance of one approach against another.
以市场基准为原则调整价格是无可厚非的，但是对此的方法并不是固定的，可以进行灵活地调整。
Steps toward more market-based pricing are welcome, but the formula, which has not been published, is still being applied flexibly.
要获得基准测试结果报告，最容易的方法是调用 Benchmark.toString方法。
The easiest way to get a benchmark results report is to call the Benchmark.toString method.
关于OSR的最后一点提示：通常，只有程序员很懒惰，把所有东西都放在一个方法(比如main)中时，它才会给基准测试带来性能问题。
One final comment about OSR: it is usually only a performance problem in benchmarking, when programmers are lazy and put everything in a single method such as main.
一旦基准利率接近0，无论经济前景多么悲观，这个方法都不再奏效了。
Once the base rate gets close to zero, that approach no longer works, however chilly the economic outlook.
如有可能，提供清除脚本及返回基准线的方法。
When possible, provide cleanup scripts and a way to return to the baseline.
在基准测试环境中使用的度量方法不一定可以应用到生产环境，在生产环境中，工作负载可能发生变化，不仅仅是每天、每小时有变化，甚至每分钟都有变化。
Measurements used in a benchmarking environment do not necessarily apply to a production environment, where the workload can change, not only day-to-day and hour-to-hour, but minute-to-minute.
周一，位于美国弗吉尼亚州诺福克市的东维吉尼亚医学院发布了这份研究。对1000名受试者的研究显示累计睡眠时间和体重指数刚好成反比，体重指数是一种以身高为基准来衡量体重的方法。
