FreeBSD 7.0 has some new features, including support for ZFS, journaled filesystems, and SCTP, as well as dramatic improvements in performance and SMP scalability. Some benchmarks show linear scaling up to eight CPUs. Many workloads see a significant performance improvement with multicore systems.
It is currently available for the AMD64, i386, ia64, pc98, and powerpc architectures. The version for the sparc64 architecture will become available in a few days.
