What happened to my vlan?
Contributed by rueda on Wed Feb 22 08:54:42 2017 (GMT)
from the one-step-back-for-two-steps-forward dept.

Hrvoje Popovski kindly wrote in to point out that Martin Pieuchot (mpi@) has written a piece entitled What happened to my vlan?.

The piece begins:

A long term goal of the effort I'm driving to unlock OpenBSD's Network Stack is obviously to increase performances. So I'd understand that you find confusing when some of our changes introduce performance regressions.

Understanding the modernization of the OpenBSD network stack, part 2: A story of if_get(9)
Contributed by pitrh on Fri Jan 13 15:50:03 2017 (GMT)
from the puffy the interface juggler dept.

Martin Pieuchot has written another article chronicling the modernization of the network stack. Martin writes,

I wrote a second article about the network MP thingy.

The article talks about a new API built on top of a generic solution for a MP problem.

The article, A story of if_get(9), is a followup to the part one article we featured earlier as Understanding the modernization of the OpenBSD network stack, part 1: ART single thread performances.

Read both for a deep dive in the ongoing and exciting work going on right now in the OpenBSD network stack.

Needless to say, editors@ really look forward to seeing more articles in this series.
