The bandwidth of storage systems varies by who-knows-how-many orders of magnitude. If 200ms is correct for one system then it is vastly incorrect for another. A more suitable clock for this estimate would be "per 200 requests", for a block-based BDI. Also of course the bandwidth of a particular BDI varies vastly depending on workload. For the purpose of this work, that's probably a desirable thing. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
