By default MD tries to be fair and allow partially written stripes the same access to the disk as fully written stripes to prevent starvation for little writers. However, you can sometimes eek out more streaming performance at the cost of fairness by increasing this value (where 0 == never let a preread pass a full-stripe-write).
I believe XFS optimises for full stripe writes, so perhaps this setting is of more benefit for other file systems?
As always I guess, real world testing is the only answer. Regards, Richard -- 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
