“Performance delta focuses on the relationship of each dedup routine compared to un-deduped storage on the same hardware. It’s the same data but organized differently.
Fast dedup outperforms legacy dedup by almost 25% of the raw performance.“

“OpenZFS 2.2.5 is now available as the newest stable update to this open-source ZFS file-system implementation for Linux and FreeBSD systems.
OpenZFS 2.2.5 adds official support now for Linux 6.9 while continuing to retain support back through Linux 4.18 kernels. Yes, Linux 6.10 is out as stable now for the past three weeks and there are some Linux 6.10 compatibility patches in OpenZFS 2.2.5 but apparently not yet enough to claim full support. On the FreeBSD side there is support with FreeBSD 12.2 and later.
Besides supporting Linux 6.9 and some Linux 6.10 bits, OpenZFS 2.2.5 brings dozens of various bug fixes. There is improved dnode hashing, cleaning up buffer re-compression in L2ARC, various libspl fixes, various ZTS fixes, and other fixes scattered throughout.”
