Nicola,
which kernel are you using ?
2.4 vs 2.6 performance on my machine (and same problem on different machines)
raid5 13 disks
2.4: write 100MB/s read 140MB/s
2.6 write 100MB/s read 280MB/s - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
