Subject: [RFC PATCH 0/2] mkfs: large fs IO scalability improvements
Date: Tue, 4 Sep 2018 18:28:55 +1000 [thread overview]
Message-ID: <20180904082857.2180-1-david@fromorbit.com> (raw)
Hi folks,
These are the patches that fell out of looking at why making an 8EB
filesystem was taking so long on one of my faster VMs. Sure, it's
millions of IOs, but there was 3x as much IO as there should have
been, and a large amount of it was unexpected, inefficient RMW
cycles cycles during free list initialisation.
Details in the patches, I don't think there's anything controversial
in them. Let me know what you think.
Cheers,
Dave.
