| I don't know how much overhead the locking system that FreeBSD is | using will impose on a uniprocessor machine, but I would guess | anywhere from 10%-25% slower. I think that only 10% would be pretty | impressive for the very first release. Again -- this is a *guess*. Any idea if a custom kernel can completely leave out the SMP code and end up comparable to 4.x? | They are taking a very reasonable course of getting it correct before | worrying about getting it as fast as possible... Which is the best way to do it, clearly. jm -- There are only 10 types of people in this world: those who understand binary, and those who don't.
