For the most part, you don't want to optimize for speed, or bandwidth utilization, or any other type of efficiency — but for something more nebulous: user satisfaction.

在大多数情况下，优化的目标并不是速度、带宽利用率或者其他效率指标，而是更模糊的目标：用户满意度。

In this thesis, we adopt the bandwidth-efficient OFDM system, which can adjust efficiency of bandwidth usage.

在本论文中，我们采用高频宽效率的正交分频多工调变系统。

The prediction strategy replicates the data in the local nodes before data access, it optimizes the efficiency of data access by utilizing the unoccupied bandwidth of the networks.

数据访问预测算法通过在网络空闲时，提前将需要访问的数据复制到本地，利用网络的空闲带宽减少远程数据访问延迟来提高数据访问效率。

Things like the number of computer instructions per clock cycle, the bandwidth of the RAM bus, and the overall efficiency of the architecture are at least as important as the raw clock speed at which a processor runs.
