Is it worth considering compling a generic MPPF kernel for user convenience

Tom Smyth
Hello,

I was wondering what devs / more experienced users think about
having BSDMPPF kernel as an option in the upcoming release
so that users could opt to test that  by selecting alternate BSDMPPF kernel
(without having to re-compile the kernel)

the tested benefits on a  PC engines  apuc2 is at least 2x performance
from my lab testing here

I think having a higher install base of consistently complied generic
kernels with
pf enabled would be beneficial

what do the more experienced users of OpenBSD think about this?

are there any down sides with this approach ?

Thanks,

Tom Smyth

No, this is not our style, it very much doesn't fit the development
process to have users running prototype code for 6 months.

And anyways why do you want this, since pf is going away.

With MPPF it can go away almost ~5x as fast on a 6-core machine.

Ok,  under stood re ,prototype code...
thought the Project was being extra conservative :) and
that more people trying MPPF would be helpful, but if it aint
ready for release it aint ready for release

re PF going away... I thought that was a Calendar Coincidence...
now im feeling a slight up tick in my blood pressure  :)

MPPF is multi processor for pf or what? Where can i learn more about it? I was searching sources but could not find anything related to "MPPF", any clue?

thanks,

Hi, you can re-compile the BSD kernel to allow multi Processor PF,
(but it is deemd by people who know more about PF and Programming
than my self that it is not fully up to OpenBSD standards for Release yet

I was referring to it as BSDMPPF as a continuation of the BSD vs BSDMP
kernel ...

sorry for the confusion that I have caused in this case...
