摘　　要：JVM中堆的默认配置有时并不适用于大型程序,这会使系统在垃圾收集上耗费过多的时间,进而导致程序性能下降。简要分析了HotSpot JVM垃圾收集机制,然后结合已有研究,以一个网管程序为例,提出了通过调整垃圾收集提高程序运行效能的方法。The garbage collection mechanism of JVM may sometimes work inefficiently with the default settings of the heap in large applications. It will degrade program＇s performance by taking a lot of time in garbage collection. In this paper, The Hotspot JVM garbage collection mechanism is briefly analyzed. With a network management application as a background, a method was proposed for the purpose of performance improvement.
