Microkernel operating systems, like L4 and QNX beg to differ.

What is your claim?

Are you going to claim they do networking faster than OpenBSD?

Given the actual use in production systems, I guess so.

How fast does OpenBSD do radio networking on mobile phones?

How fast does OpenBSD do CAN networking on car systems and factory installations, with real time constraints?

You're arguing a strawman.

No, if OpenBSD was actually better for those use cases I guess companies would have noticed it already, instead of paying for microkernels with slower performance.

They absolutely do have worse networking performance. Just not enough to matter for those applications.

If OpenBSD is so great serving network requests why isn't it taking over the world of cloud services?

Because cloud providers would rather pay for a little more hardware than have to hire or train an ops team that understands OpenBSD?
