No, I failed to tune other flags... That's why I started this thread...
I understand it's a trade-off whether to expose the design docs. Not exposing

The op seen in the logs is a rowset compaction, which takes existing
diskrowsets and rewrites them. It's not a flush, which writes data in
memory to disk, so I don't think the flush_threshold_mb is relevant. Rowset
compaction is done to reduce the amount of overlap of rowsets in primary
