La campagne de donation en faveur du projet NetBSD est arrivée à son terme gràace aux donations de chacun, mais aussi de l'aide provenant de Google. Ceci va permettre en autre de travailler et améliorer le support SMP. Pour de plus amples informations sur ce sujet :  =>http://netbsd.mcom.fr/changes/#fundraising2007pr.

La boule de geisha!:
Ca y est après de longues heures à tapoter leur clavier pour nous offrir tant que belles nouveautés et bugs fixes, nos lutins favoris nous offrent la version 7.0 de FreeBSD :-)

Je ne vais pas faire nouveau :

  - 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.
