Hi All I am trying measure the RAID 5 Read numbers on linux kernel-2.6.21 and kernel 2.6.27 the numbers are lower on later kernel (2.6.27). Iam measuring the numbers using "time dd" command (4GB ). Is any valid reason for this, or Am missing anything in the process. Can anybody help me in analyze this problem.
