If that improves, you can try 512, but that might not make a > further difference. Thanks for your advice. The performance has the following improvement. data=journal JBD2_NR_BATCH=64 -> 398MB/s data=journal JBD2_NR_BATCH=256 -> 412MB/s data=ordered ->1.1GB/s Do you have any other suggestions? -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
