[Unbound-users] Performance of Caching Name Servers

Hi,

Is the machine a multi cpu, multi-core machine? You can increase
num-threads in the config file.

Are you sure that both bind and unbound are treated the same by resperf?
What does resperf measure (what queries does it send?)

What is the bind configuration that you use and what is the unbound
configuration that you use? Are they acting as full resolvers, or do
they forward to another host?

Best regards,
~   Wouter
