Not scheduled to drop until tomorrow, so anything on this page is probably subject to change. Still:

TCP stack is now running in parallel on multiple CPUs. Up to 8 threads are used to process TCP traffic.

That feels like it might be a big change.

I upgraded my OpenBSD machines a few hours ago, and I'm still not entirely sure whether I notice any obvious TCP speed improvement. Then again, they're not really high-load computers. Maybe people with a higher throughput will be amazed.

Kinda surprised OpenBSD supports the Raspberry Pi 5 now, but "bigger" brother FreeBSD does not.

FreeBSD is not really curious about being as portable as possible, I think. And it is somewhat larger, indeed, so it's not quite as easy to support more platforms.

Yeah isn’t netbsd the BSD focused on portability and platform support?

Yes, and OpenBSD being a fork of NetBSD still carries some of that spirit.

And both of those have very minimal ports compared to Linux. Notably in modern arm/riscv. Netbsd has really fallen behind.

Still better than the none of freebsd.

I mean, are we surprised? Linux has on the order of millions times more users and funds (probably not developers though, but who knows). Thus, if there is any financial viability of a port I am certainly expecting Linux to "move" first. Rather, I am impressed that OpenBSD and NetBSD are keeping up as well as they do.

NetBSD and OpenBSD support “old” hardware notably longer than Linux does though. OpenBSD having dropped the VAX is not that long ago.

Yeah I suppose.

But OpenBSD forked from NetBSD like, what, 30 years ago?
