Probably even more crucial, setting compression=on is very likely to make ZFS performance even better than ext4, even on a single disk.

- Fnoord 5y agoThis and encryption seem mutually exclusive (for me with OpenZFS @ Ubuntu 21.04).
- throw0101a 5y agoThey occur at different layers: > OpenZFS native encryption splits the difference: it operates atop the normal ZFS storage layers and therefore doesn't nerf ZFS' own integrity guarantees. But it also doesn't interfere with ZFS compression—data is compressed prior to being saved to an encrypted dataset or zvol. * https://arstechnica.com/gadgets/2021/06/a-quick-start-guide-to-openzfs-native-encryption/ https://arstechnica.com/gadgets/2021/06/a-quick-start-guide-...
- chungy 5y agoNo, they are not. Compression happens on the plaintext data, and encryption applies post-compression.
