Not even close.

Performance is always important. On mobile CPUs every milliwatt counts and on desktop or server CPUs where performance is their whole reason to exist.
Honestly, though, it doesn't matter. I was only commenting on monolithic kernel security, not performance.
I maintain that for iot, something like sel4 is necessary. Arm is promoting their, closed source, ukernel mbed os, for just such devices. I'd much rather have the open source sel4 in that position.

Suxx for sure!
Of course OpenBSD suxx! Its nearly unusable for anyone but bunch of lunatics who do not care about doing anything useful at all.
These guys turned OS development and administration into religion where they pray their quasi-god Theo. And of course there are counterproductive rituals instead of well thought actions all the time. Its so damn productive to use CVS as of 2015. Even outdated SVN scrap is way too new for openbsd, not to mention things like GIT. That's what I call retarded and completely counterproductive project management.
They tell us:
missing of snapshot capabilities with the FFS file-system

In fact this time starts here and now: cheap, low powered, small, coin sized, SD-card-sized computers already have CPUs capable of running Linux and more or less supported, even by mainline kernel. Yet they have decent networking, up to being able to work as full-fledged wi-fi access point. Yet, it costs about $10 or maybe $15 at most.
I think it is pretty clear what will make IoT possible and useful: it will be Linux. Sure, maybe 0.005% of market will need some uber-secure, super-crash-resistant devices. But these are inherently costly, have awful R&D costs, lack features everyone expects these days and you can't expect high demand on such devices. Just like you can't expect to sell armored car to Average Joe: even if it can withstand bazooka shot, Average Joe hardly needs this feature and not willing to pay for that.
Good project management is all about keeping things adequately balanced. Something that BSD zealots and microkernel dreamers fail to do all the time.
