X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 15 Oct 2007 16:04:17 -0000 --=-jfCOyommEVZJL1nAr7Dj Content-Type: text/plain Content-Transfer-Encoding: quoted-printable I think it's fairly common knowledge by now but... The ULE scheduler is "back" and has been doing VERY nicely. We actually had an internal discussion about making it the default for 7.0. In the end it was decided that ULE "just barely missed the bus". Its performance makes giving it a try once 7.0 comes out definitely worthwhile but it was just barely "too new" for us to be truly comfortable with changing it to be the default. We'd like it to have the exposure of one release cycle (7.0-REL) before it becomes the default. For now we're planning to make it the default for 7.1-REL. To that end either Jeff or I will be switching the default scheduler in 8.0-CURRENT for the amd64 and i386 architectures over to ULE in a couple days (Wednesday-ish). --=20 Ken Smith - From there to here, from here to | kensmith@cse.buffalo.edu there, funny things are everywhere. | - Theodore Geisel | --=-jfCOyommEVZJL1nAr7Dj Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQBHE494/G14VSmup/YRAlY2AJ4iYAXkcEAoazuA+UmgSTeQtSRrdwCePvex ZEJmejh4c7bAIpO86Txa6yY= =eRrl -----END PGP SIGNATURE----- --=-jfCOyommEVZJL1nAr7Dj--
