Hi Pedro,
I've used resperf (part of the dnsperf set of tools) to load-test my recursors
and measure the differences in capacity when making changes to different
configurations and adding/removing resources. See project on GitHub here:
https://github.com/DNSPerf/dnsperf .

Hi Pedro,
There is always a bottleneck. Wether you notice it depends on the load against
the system. You will notice it if your system drops packets from a certain load
on. From there you can try to improve by tuning "things"
such as Recursor config, NIC config, kernel parameter, firewall ...
