The second technique is to reduce the polling overhead of the JMX exposed memory pools further by implementing the listening collector pattern instead of a polling pattern.
第二个技巧是使用监控收集模式代替轮询模式，从而进一步减少JMX公开内存池的轮询开销。
Two additional techniques not implemented in these examples can improve the JMX collector's efficiency and reduce the overhead of running it against the target JVM.
这些示例中未实现的两个额外技巧可以改进JMX收集器的效率，并减少它在目标JVM中运行所需的开销。
This paper introduces the working principle of the dust collector for the multi-purpose overhead crane in the production of alumina, technical performance requirement to the dust collector as well as the suction and the length of the filter bag, etc.
介绍铝电解焙烧阳极生产中焙烧多功能天车所使用脉冲除尘器的工作原理、除尘设备应达到的技术性能，以及进气方式和滤袋长度的选型等。
Reference counting is simple, but requires significant assistance from the compiler and imposes overhead on the mutator (the term for the user program, from the perspective of the garbage collector).
引用计数很简单，但是需要编译器的重要配合，并且增加了赋值函数（mutator）的开销（这个术语是针对用户程序的，是从垃圾收集器的角度来看的）。
Usage of XPCOM has been decreased in many places over the years, and its resource overhead was reduced by the new cycle collector.
