摘　　要：针对目前LinuxNC中Java虚拟机运行Java程序存在的性能问题。提出了一种优化方案,以直接线索式解释器为基础优化技术,并设计3项扩展优化点突出优化效果。旨在兼顾LinuxNC现有的硬件和软件条件,有效地提升Java虚拟机运行效率,同时保证较低的CPU和内存成本。At present, the performance of Java virtual machine in Linux Network Computer（NC） is relatively low. An optimization scheme was proposed, which based on the direct threaded interpreter, and three extended techniques were designed to stand out the effect of optimization. In this way, considered the conditions of hardware and software, the executing efficiency of Java VM can be upgraded. Besides, this project can also reduce the cost of CPU and memory.
