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.
Au passage, je vais faire un petit mirroir :
