当不少企业正在为升级到 Windows2000做准备的时候,有更多的企业在考虑新的 PC 采购方针。新型操作系统与越来越复杂的末端用户应用环境对 PC 整体的性能要求越来越高。比如,一些测试数据显示,要想在 Windows 2000专业版上获得与原来在 Windows NT4.0上同等的性能,需要将原有系统的处理器时钟频率增高200MHz,以获取15～20%的性能补充。随着应用负荷增加,二者间的性能差距还将增大。解决这一问题最常见的方法是提高处理器的时钟频率,但测试显示,这并非最好的方法。利用Windows 2000专业版中对 SMP(对称多处理)技术的支持,在企业中部署双处理器台式机将获得更好的收效。早期的 Windows NT 3.x/4.x 操作系统对 SMP 的支持非常有限,只有某些特定的应用才能享受到双处理器的好处,而多数主流应用性能并未得到提升,因此
When many companies are preparing to upgrade to Windows2000, more companies are considering the new PC procurement guidelines. New operating systems and increasingly complex end-user applications require increasingly high performance for the PC as a whole. For example, some test data show that in order to get the same performance on Windows 2000 Professional as it was on Windows NT 4.0, you need to increase the processor clock of the old system by 200MHz to get a 15-20% performance boost . As the application load increases, the performance gap between the two will also increase. The most common way to solve this problem is to increase the processor’s clock frequency, but tests show that this is not the best approach. With the support for SMP (symmetric multiprocessing) technology in Windows 2000 Professional, deploying dual-processor desktops in the enterprise will yield better results. Earlier Windows NT 3.x / 4.x operating system support for SMP is very limited, only some specific applications to enjoy the benefits of dual-processor, and most of the mainstream application performance has not been improved, so
