Well,
Thank you for on topic answers. I've seen the -pthread parameters on
some ports' compile, but I thought is an alias for process. I will
read about them.
Damn, am I the only one who gets mad when receiving a link to
wikipedia ? It looks like a sindrome on internet.
I'm confused about

But, yeah, if you want to maximize your 48 core AMD box in a data center and
you don't see make -j48 as a practical application, OpenBSD may not be
there yet for you. I don't have anything with more than 4 cores, so it was

Hi folks,
I will reformulate the question. Sorry for this, but it sleeps off topic.
So, I'm interested about Intel Core 2 Duo family and i3, i5, i7
families. I don't know what SMP is about.
I remember UNIX has no threads, just processes spawn by fork().
Having this in mind, will a processor

and etc.
Yes, it will use all your cores.
I don't understand your question about blade servers, but they are
just a different form factor of the essentially the same hardware. If
the hardware is supported SMP should work just fine.
PS: SMP is what lets you use all your cores:

The above paper has nothing to do with what's called being rthreads in OpenBSD.
A more appropriate paper from 1995 would be this one,

you're wrong. my OpenBSD SMP boxes (no, no 48 cores) do very well.
as long as the load is userland-driven we scale fine.

Also, both tests were run with the MP kernel, so even the single-task

Hello,
I got the idea from FAQ that OpenBSD is not using more than one core
from multicore processors.
Pretending I got it right, what's the benefit to buy an Intel Core 2
Duo ? Just the bigger cache and some extra instructions?
Is there a difference in how OpenBSD handles let's say a multicore

This is my not-so-technical understanding.
OpenBSD's current SMP status:
- The kernel uses a single lock for shared data. My understanding is
that this means that the kernel itself doesn't benefit from SMP as
much as it could otherwise, but it does use multiple cores. (I
