> Here's the same situation on a 128 GB / 32 core server. It is doing some heavy

These look like the new xfs inode cache shrinker is active. The dd is
generating memory pressure, and kswapd potentially running the slab shrinkers
reclaiming cached inodes. Can you show the output of slabtop before the dd and
while it is running?
Cheers,
Dave.
