作为计算机心脏的处理器的时钟频率四年来提升了4倍。处理器速度的提升推动了其他技术的进步。硬盘的性能提离了近2倍,LAN 的性能已达到原来的10倍,系统总线的频率也随之一跃而由原来的66MHz 上升至目前的100MHz。一系列系统设备速度的提升,使各设备的传输速度趋于同步,数据传输的瓶颈效应正在逐步缩小,随着二级高速缓存内置于 Pentium Pro 及 PentiumⅡ处理器中,进一步提高了缓存本身的速度,降低了系统总线的占用时间,从而为系统总线节省了更多的时间以处理其他外设
The clock speed of the processor as a computer heart has quadrupled in four years. Advances in processor speed have advanced other technologies. The performance of the hard disk lift nearly 2 times, LAN performance has reached 10 times the original, the system bus frequency also jumped from the original 66MHz to the current 100MHz. As the speed of a series of system devices increases, the transmission speed of each device tends to be synchronized. The bottleneck effect of data transmission is gradually reduced. With the second level cache built into the Pentium Pro and Pentium II processors, the speed of the cache itself is further improved , Reducing the system bus occupancy time, thus saving more time for the system bus to handle other peripherals
