I've increased from 64 to 8192 PGs Do you mean you used PG splitting? You should split PGs by a factor of 2x at a time. So to get from 64 to 8192, do 64->128, then 128->256, …, 4096->8192. Splitting is costly — it should be done with caution, even if you don’t have much data in the pools. Cheers, Dan
