A long time ago, I used to compile SMP into my kernels just on the coolness factor, and on the promise that 'one day, soon, I'll get me a decent machine' :)SMP kernels run fine on single processor machines. I have repeatedly been told, however, that this bears a considerable performance hit on some hardware. Can anybody confirm or deny this? Even small hints would be appreciated.
But I quit doing that at some point, after someone (authoritative, but I can't remember the details) pointed out that it added complexity, debugging issues, etc. Given that I *already* have problems with PPC kernels -- latency/lockups, (preempting?), alsa sound, video res, etc., I personally wouldn't go near this until I'm fairly confident that the other stuff is solid in its own right.
But then, I'm just a luser, not a kernel maintainer ;D -- Lee Braiden lee_b@member.fsf.org
