摘　　要：门(Door)技术是Sun公司开发的Solaris操作系统中的一个进程间通信的功能.通过分析门(Door)机制的基本原理和结构,编写了基于Solaris门(Door)机制的客户/服务器的测试程序,并利用Solaris操作系统提供的内核分析工具对计算机内存的使用情况进行了详细的分析,获得了确定的结果.实现了在门(Door)机制的结构下对内存的共享,提高了内存的利用率,并且对于相同并发线程数量与利用率的关系给出了分析与结论.Door is is the development of Sun Solaris operating system in inter-process communication. By analyzing the basic principles and structure of door, we compile client/server testing program based on Solaris door, use analytical tools provided by Solaris operating system kernel to carry out a detailed analysis of the use of computer memory and obtain the certain results. Shared memory is achieved under the structure of door mechanism, together with the utilization of memory increased. Determinate conclusions are made between the number of concurrent threads and the usage of memory.
