Hi, yes I'm also puzzled by this. The cluster is certainly not underpowered, running on baremetal with 8x SSD in ZFS stripe of mirrors, 128 GB RAM and shared_buffers is set to 8GB.
other related settings: wal_buffers = 128MB checkpoint_timeout = 60min max_wal_size = 8GB min_wal_size = 1GB checkpoint_completion_target = 0.9 I wonder if checkpoint_timeout should be lowered?
