Linux Distribution: FreeBSD
Url: http://www.freebsd.org/
FreeBSD is an advanced operating system for x86 compatible (including Pentium® and Athlon�), amd64 compatible (including Opteron�, Athlon 64, and EM64T), Alpha/AXP, IA-64, PC-98 and UltraSPARC® architectures.
Linux Release Details:
FreeBSD 7.0 has been released
The FreeBSD Release Engineering Team is pleased to announce the availability of FreeBSD 7.0-RELEASE. This is the first release from the 7-STABLE branch which introduces many new features along with many improvements to functionality present in the earlier branches.
Some of the highlights:

  • Dramatic improvements in performance and SMP scalability shown by various database and other benchmarks, in some cases showing peak performance improvements as high as 350% over FreeBSD 6.X under normal loads and 1500% at high loads. When compared with the best performing Linux kernel (2.6.22 or 2.6.24) performance is 15% better. Results are from benchmarks used to analyze and improve system performance, results with your specific work load may vary. Some of the changes that contribute to this improvement are:



    • The 1:1 libthr threading model is now the default.

    • Finer-grained IPC, networking, and scheduler locking.

    • A major focus on optimizing the SMP architecture that was put in place during the 5.x and 6.x branches.



  • Some benchmarks show linear scaling up to 8 CPUs. Many workloads see a significant performance improvement with multicore systems.

  • The ULE scheduler is vastly improved, providing improved performance and interactive response (the 4BSD scheduler is still the default for 7.0 but ULE may become the default for 7.1).

  • Experimental support for Sun's ZFS filesystem.

  • gjournal can be used to set up journaled filesystems, gvirstor can be used as a virtualized storage provider.

  • Read-only support for the XFS filesystem.

  • The unionfs filesystem has been fixed.

  • iSCSI initiator.

  • TSO and LRO support for some network drivers.

  • Experimental SCTP (Stream Control Transmission Protocol) support (FreeBSD's being the reference implementation).

  • Much improved wireless (802.11) support.

  • Network link aggregation/trunking (lagg(4)) imported from OpenBSD.

  • JIT compilation to turn BPF into native code, improving packet capture performance.

  • Much improved support for embedded system development for boards based on the ARM architecture.

  • jemalloc, a new and highly scalable user-level memory allocator.

  • freebsd-update(8) provides officially supported binary upgrades to new releases in addition to security fixes and errata patches.

  • X.Org 7.3, KDE 3.5.8, GNOME 2.20.2.

  • GNU C compiler 4.2.1.

  • BIND 9.4.2.
