Hi, After reading few sources, I decided to use dedicated NVMe Disk with native replication. Those benchmarks and performances I was referred for internal use only. Not much data stored there. I believe for production usages, it will deliver more trouble than advantages. Thanks, Gencer. On 17.10.2020 18:39:44, Gencer W.

Maybe i can get much better performance on smaller object size. Haven't tried actually. Why are you not recommending this setup actually? Gencer.

For example; Currently defaults are: Object size (4MB) and Stripe Unit (None) Features: Deep flatten + Layering + Exclusive Lock + Object Map + FastDiff Should I use as is or should I use 16KB of object size and different sets of features for PostgreSQL?
