What do you run now? I currently use FreeBSD because it has binary update&#x2F;upgrade support, currently seems to have better smp than OpenBSD, and the network stack is fast. Also looking forward to some of the network performance improvements[1] coming in 11.<p>I have been hearing good things about DragonflyBSD lately though too.<p>[1]: <a href="https:&#x2F;&#x2F;github.com&#x2F;ocochard&#x2F;netbenches&#x2F;tree&#x2F;master&#x2F;Atom_C2558_4Cores-Intel_i350&#x2F;fastforwarding-pf-ipfw&#x2F;results&#x2F;fbsd11-routing.r287531" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ocochard&#x2F;netbenches&#x2F;tree&#x2F;master&#x2F;Atom_C255...</a>
