ULE Now The Default Scheduler On FreeBSD

Posted by timothy on from the ule-stole-my-prom-date dept.

Dan writes "FreeBSD's Jeff Roberson says that the ULE scheduler has entered into its probationary period as the default scheduler on FreeBSD. He says that if all goes well, it will remain the default through the rest of FreeBSD 5.* releases. He is requesting you to switch over and test it. The ULE scheduler was designed to address the growing needs of FreeBSD on SMP/SMT platforms and under heavy workloads. It supports CPU affinity and has constant execution time regardless of the number of threads."

    So, the OpenBSD guys are wasting their time rewriting software that already exists in a free form, and you're questioning the benefit of the GNU/KFreeBSD project?

    The point is : They don't see GPL as free enough. And since OpenBSD, like other BSD, is not just a kernel, they have to care about licenses for all program shipped with their OS. Go check OpenBSD Copyright Policy

    Well, they actually *do* help keep the GNU toolset portable and clean. Even if they aren't used, using the same stuff on more than one OS exposes problems before they become a remote root exploit.

    Sure I like BSD. Says so in my sig. But if someone else does things right, I'm not going to yell at them.

    Besides, with the GNU toolset on the FreeBSD kernel, you can set up a jail on the FreeBSD side, and then if you want both you can have both. There are differences, it's annoying sometimes, I'm sure some people want both.

    When someone might yell at me, it has to be OpenBSD.

    Security updates are still released for older FreeBSD versions, as well as NetBSD versions. Have a look at http://www.netbsd.org/Security/ and you will see that security updates are made for NetBSD 1.5. NetBSD 1.5 was released at the end of 2000, yep, that is over three years ago. It is true that the FreeBSD EOL is shorter, but it is not hard to track a -STABLE branch.

    Most of these tools are being removed/replaced from the OpenBSD source tree. Several of these are also being removed/replaced from the FreeBSd source tree. Not sure if there are any projects along these line for NetBSD.

    Check out libtar, the BSD replacement for GNU tar. BSD awk and sed are also in the works, as is a BSD grep.
