Oh me too! dual P3 1Ghz, 1GB ram, 2.2.20RAID, ext2, Mylex extremeraid 2000 hardware RAID5, six IBM 36LZX 10k RPM 36GB U160 SCSI drives. 1.89 seconds same system, but mylex hardware RAID0 instead of raid5, still 1.89 seconds. same system, but with a 3ware 7850 with six maxtor 160GB drives.... 1.89 seconds. same system, but with two IBM 18LZX 18GB 10k RPM SCSI drives on an onboard adaptec U160 controller and linux software RAID0... 1.88 seconds. It seems disk+controller doesn't matter one bit for this test. Now a new system: dual AthlonXP1800, 1GB ram, 2.4.16, ext3, 3ware 7410 RAID0, two maxtor 160GB drives... 2.38 seconds Conclusion: either ext3 or the 2.4 kernel are slow, as the second machine as has PC2100 RAM vs PC133 and 1.5Ghz athlons vs 1Ghz pentiumIIIs. It should be faster, not slower. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
