实验结果表明，该方法能够充分利用动态松弛时间，有效控制调整开销，实现较高的能耗优化率。
Experiments show that this approach can achieve high energy reduction ratio by exploiting the dynamic slack time sufficiently and controlling the scaling overheads effectively.
正如上文所示的固定堆示例，应用程序可能有时的运行速度比调整前快，但仍然由未改变的GC开销甚至更长的平均暂停时间表示。
As the example of fixing the heap above showed, an application may sometimes run faster than it did before being tuned but still be marked by an unchanged GC overhead or even longer mean pauses.
在调整时，一定要考虑大型数据库的额外开销和进行全文搜索的频率。
When sizing, make sure you take into consideration the extra cost of large databases and frequency of full-text searches.
JIT通过将代码编译成机器码，这样可以减少翻译Python指令的时间，以此提高代码的执行速度。 “在CPython里，” Winter 解释道，“这一部分的开销很大；在这方面只做了较小的调整就使CPython 2.7有了近15%速度提升。”
Using a JIT will speed up execution by compiling to machine code, thus eliminating the overhead of fetching, decoding, and dispatching Python opcodes.
2010年，城市年平均收入约2900美元，乡村年平均收入约900美元（在乡村，根据低开销来调整，可以减小差距）。
In 2010, annual per-capita income was about $2,900 in cities and about $900 in rural areas. (Adjusting for lower costs in rural areas reduces this gap.)
鉴于环保开销，游客乘上双动力巴士，饭店也开始提倡调整冷气温度，让大自然有优先享受舒适权。
In light of the environmental cost, tourists now ride on hybrid buses and hotels are taking initiatives to adjust air conditioner temperature levels to prioritise nature over the luxury of comfort.
轮询的开销很高，可能需要对其进行调整，在缓存清理算法的反应速度与轮询调用次数之间进行折中。
This polling is expensive and might need to be adjusted as a tradeoff between reaction speed of the cache-trimming algorithm and number of polling calls made.
