After several weeks of testing and a discussion at the meetBSD 2010 conference I have successfully imported into the FreeBSD operating system (development branch 9-CURRENT) an update of the ZFS file system to version 15.
What is new in this version?
1.
Stability - more mature ZFS code, comparable to Solaris 10 update 8 with latest bugfixes
2.
Compatibility - Solaris 10 update 8 default ZFS pools can now be imported into FreeBSD
3.
Features - user and group quotas (ZFS-internal) are very useful for intranet fileservers that want to use ZFS
4.
Speed - my real-world benchmarks give a 15-20% RPS yield in PHP webserver workloads with codebase on ZFS
The new version will take 2 months of testing and if there are no serious issues I will import it on 2010-09-12 into the 8-STABLE branch.

The update is backwards and forwards compatible - old versions of the zfs and zpool utilities work with the new kernel module and new versions of these utilities support the old kernel module.
