就信息检索来说,研究结果表明,250ms的系统总响应时间可获得最佳的结果.根据他们的分析,Rogers和Russell允许数据传输时间不超过系统总响应时间的30%,即最长为75ms.在检索一个6,200字节文本对象时,所需最高数据传输速率为0.7Mbps.对一个50KB CAD/CAM对象来说,所需最高数据传输速率为5.3MbPs.一个144KB的大型扫描办公图像需要15.4Mbps.(一个1MB生产图像需要106Mbps的最高传输速率才能达到250ms的目标.)就计算应用来说,他们研究了远程过程调用的需要.此时,所传输的对象为200字节,而所需的传输时间为0.0001秒.在这种情况下,16Mbps是所需的最高传输速率、为了在
For information retrieval, the results show that the 250ms total system response time to get the best results.According to their analysis, Rogers and Russell allow data transmission time does not exceed 30% of the total system response time, which is up to 75ms . The maximum data transfer rate required for retrieving a 6,200 byte text object is 0.7 Mbps. The maximum data transfer rate required for a 50KB CAD / CAM object is 5.3MbPs. A large 144KB office scan image requires 15.4 Mbps. (A 1MB production image requires a maximum transfer rate of 106Mbps for a 250ms target.) For computing applications, they looked at the need for remote procedure calls when the object being transferred was 200 bytes and the required Of the transmission time is 0.0001 seconds.In this case, 16Mbps is the maximum transmission rate required in order to
