Device-level IO blockingDevice-level IO blockingPosted Oct 2, 2007 17:30 UTC (Tue) by njs (guest, #40338)In reply to: Device-level IO blocking by Jel Parent article: Smarter write throttling
I doubt that would make much difference -- the goal is that the rate at which writes are queued should match the rate at which writes are completed. Since there is a buffer, these rates don't have to match in fine detail; they only have to match on average.
Even over long time periods, different devices will be more or less fast; but the differences within a device tend (I believe) to wash out over any time period longer than a few hundred milliseconds.
