Packet perf

[miekg]

I'm playing around on packet.net and I'm finally seeing figures that I have been seeing on my local machine. I.e. a beefy type1 server does (locally!):

Queries per second:   223763.430646 qps

Doing the same thing over the network yields (obviously) much less:

Queries per second:   47829.543277 qps

[miekg]

Done on Debian 8 - with really old 3.16 kernel

[miekg]

udp.go does (localhost):

 Queries per second:   360485.732524 qps

[miekg]

Can't get NSD to give me reliable figures though :(

NSD version 4.1.0
