The code is however optimized such that it throttles the DB2 engine to a maximum of 2 GB of memory and 2 cores of processing power for the database on any sized server or virtualization session.

不过，它的代码在优化之后使得 DB2 引擎在任何大小的服务器或虚拟会话上最多仅能支持 2 GB 的内存和 2 个处理器核。

Unfortunately, because of the nature of air circulation, any downward-pointing force created aerodynamically generates a backward-pointing resistance in the process just as an increase in the lift of an aircraft wing as the flaps are lowered for take-off or landing creates more drag in the process, forcing the pilot to open the engine throttles to overcome the extra wind resistance.

The engine constantly throttles up and down, not only to counter the drag on the satellite from residual air molecules in near space but also to smooth the flight of the vehicle to minimise the noise in the gravity measurements.

Upon reaching 41, 000 I pulled the Mustang's throttles back to 220 pounds per hour per engine of Jet A fuel.
