Everyone, thank you very much for helping me to learn more. Getting up to speed takes forever! I posted an idea relating to this thread, but it's more read latency rather than throughput related, but I'm not sure what the right way to link overlapping threads is, so here is how to find it: Date: Fri, 22 Apr 2016 18:14:00 -0400 Message-ID: <CAD=QJKgJ9JAgZAOSivJTL-bcLbdkP6UqGb0i6g=fS9j6XKtcLA@xxxxxxxxxxxxxx> Subject: Re: [PATCH v8 00/27][For 4.7] Btrfs: Add inband (write time) de-duplication framework WRT the original AG balanced IO optimisation problem, should I spend most of my time reading disk-io.c while looking for opportunities to optimize multi-device reads, while consulting xfs_file.c and xfs_super.c, or just xfs_super.c?
