BSDCon Europe 2002 Paper available

Contributed by jose on 2002-11-20 from the from-europe-with-love dept.

"With the presentation given by Philipp Buhler and Henning Brauer on performance tuning of OpenBSD network servers at BSDCon Europe, they have made a the paper available.

This looks like a pretty cool paper, I've been interested in tuning the performance of my OpenBSD systems for a while now. Thanks for the paper, guys, and the link.

i posted this in the ebsd message before!

i dont know what my point is :)

It's got some great tips, and these guys obviously know the kernel inside out. Cute idea for IRQ sharing too, counter intuitive, but I bet it makes a really BIG difference with quality cards.

It's nice to see other folks kernel configs and sysctl settings too, makes me warn and fuzzy to see others use similar settings.

The section on which NICs perform best was rather brief. I'd like to hear everyone's preferences.

I mostly stick with Linksys LNE100's, as they are very cheap (~$15), are compatible with practically everything (DEC/tulip compatible), perform quite well, and it's incredibly rare that I come across a defective card.

Anyone else?

I'd love to see FreeBSD's device polling ported to OpenBSD. If you want to see why this is needed, do a ping -f to an OpenBSD box on 100baseT.

application. Many of pf's newer features were needed, but it was not possible to wait for 3.1- Release, as the previous OpenBSD 2.9 firewall running IPFilter had saturated the processor at near 100% utilization at peak usage times, and delays were being noticed.

They get to talk about OpenBSD performance, and take a jab at IPF, at the same time... Yay1

Darren Reed correctly pointed out that is actually a paper on network performance monitoring than really tuning.

pb@ seems to agree. He says they lack time to provide a more detailled paper.

I want KVMspy now! :)

Experimental zero-copy for TCP and UDP transmit-side (using page-loaning) would be nice as well.

And of course pipes with page-loaning (this is on art's todo list).
