Puffy's Marathon: What's New in OpenBSD 4.2 - ONLamp.com

Contributed by dwc on from the interviewathon dept.

Federico Biancuzzi interviewed 23 OpenBSD developers, discussing some of the many new features in the 4.2 release. From the article:

Even though security is still there, this release comes with some amazing performance improvements: basic benchmarks showed PF being twice as fast, a rewrite of the TLB shootdown code for i386 and amd64 cut the time to do a full package build by 20 percent (mostly because all the forks in configure scripts have become much cheaper), and the improved frequency scaling on MP systems can help save nearly 20 percent of battery power.

And then the new features: FFS2, support for the Advanced Host Controller Interface, IP balancing in CARP, layer 7 manipulation with hoststated, Xenocara, and more!

Get the scoop from the developers on networking, PF, new hardware support, ports, filesystems, and much more. There's so much to list, but why not go read the ONLamp interview and see why you should order OpenBSD 4.2 (EU order) to support this kind of development in the future. And after installing, don't forget to send your dmesg to dmesg@openbsd.org!

        A noble spirit embiggens even the smallest FS.

    Are softdeps only usable on FFS1 filesystems or do they work for FFS2 as well? Just curious....

      Doesn't atascsi do this as the SCSI midlayer has has command queuing for ages? The interview mentioned that SATA was getting more and more features that SCSI has had for years.

        Exactly.

    An OpenBSD release just isn't the same without an Onlamp article. It's almost more fun than reading 42.html ;-), thanks Frederico!

    Oh yes, I also like it very much that my systems get faster from release to release instead of slower like some other OS's do. Thanks.
