Hi y'all.
I have a question about netmap - a novel framework for fast packet I/O.
OpenBSD packet I/O is already very fast from what i tested :)
Well i would go with Test server where i would take a month to go
through OS and setting up running as my requirements..
at least.
Then i will make migration plan and make test migrate from FreeBSD to
OpenBSD ...then will make clean Server instal and do migrate my data.
Hope this helps .;)

Does OpenBSD have any plan to support Netmap framework?
I also have a technical question about netmap and firewall relation.

Can you give it a spin ? 5.1 uses uthreads still, this problem might
appear more often

from their site:
netmap implements a special device, /dev/netmap, which is the gateway
to switch one or more network cards to netmap mode, where the card's
datapath is disconnected from the operating system.
open(/dev/netmap) returns a file descriptor that can be used with
ioctl(fd, NIOCREG, ...)

And I completely disagree.
You think what the kernel does now is simple ?

Let's be more practical here. Luigi already gives you a stub pcap library that

Sure it matters. Simple example: count
the comparison started against freebsd bpf's augmentations:
Zero-copy buffer mode
bpf devices may also operate in the BPF_BUFMODE_ZEROCOPY mode, in which
packet data is written directly into two user memory buffers by the ker-
nel, avoiding both system call and copying overhead.
