putc()开始到 Delete files in random orde 结束， 这是bonnie+作的12项测试，这12项测试依次对应12项结果，而这12项结果 又被分为了 5大类，分别是Sequential Output (写测试)，Sequential Input (读测 试)，Random Seeks(读写测试)，Sequential Create(顺序读写文件测试)和Random Create (随意读写文件测试)那么测试步骤和测试结果依次对应的顺序就是：Writing with putc() Sequential Output 的 Per ChrWriting intelligently 一 Sequential Output 的 Block Rewriting 一 Sequential Output 的 RewriteReading with getc() 一 Sequential Input 的 Per ChrReading intelligently 一 Sequential Input 的 Blockstart em 一 Random SeeksCreate files in sequential order 一Sequential Create 的 Create Stat files in sequential order 一 Sequential Create 的 ReadMDelete files in sequential order 一Sequential Create 的 DeleteCreate files in random order 一 Random Create 的 CreateStat files in random order 一 Random Create 的 ReadDelete files in random order 一 Random Create 的 Delete 每个结果中又包括了 2项数值，一个是K字节数或者文件数，另一个是%CP,就 是执行这项测试时CPU的平均占用率。对于输出结果的评价，我们认为在相等 CPU的占用率情况下，存取字节数越高表示该存储设备的吞吐量越大，自然性能 也就越好。Per Chr表示以字符为单位读写文件Block表示以block为单位读写文件Rewrite表示修改并重写已经存在的文件的每一个blockK/sec表示每秒读或写文件的速率，以K为单位%CP表示在某阶段执行操作时平均消耗的CPU可以看到，该机器的字符写速度可达8909K/sec， block写速度可达20708K/sec，字符读速度可达27673K/sec， block读速度可达80684K/sec。3.
