Everything I've seen on optimizing Postgres on ZFS
UPDATE (2021/12/21) After lots of feedback on Reddit (thanks /u/BucketOfSpinningRust!) and doing some more experimenting and digging, I've updated this post with more information -- new/updated sections are marked "Update". tl;dr - Tips for running Postgres on (Open)ZFS-on-Linux (ZoL), which I’m nicknaming “PoZoLâ€, check out the TOC (or skip to the resource list at the bottom) and browse to whatev

Ext4 VM Images - Ext4
Overview Various ext4 users have a particular use-case for system provisioning where they create a FS image, populate it with whatever files they want, and then want to reduce the image to a minimal one to conserve network bandwidth. At deploy time the minimal image is copied to a disk and expanded with resize2fs to fill the whole disk. There are a number of strategies to handle this operation, ea

GitHub - mhx/dwarfs: A fast high compression read-only file system for Linux, Windows and macOS
DwarFS is a read-only file system with a focus on achieving very high compression ratios in particular for very redundant data. This probably doesn't sound very exciting, because if it's redundant, it should compress well. However, I found that other read-only, compressed file systems don't do a very good job at making use of this redundancy. See here for a comparison with other compressed file sy
