As starting point

Also have a look at the follwoing points:
- Check if firewall is enabled and if it supports many UDP "connections"
- Check for the send/receive buffer max values for the OS
- Check the max sockets/file descriptors of the OS

Be aware that using unbound as *validating* resolver can slow down a  
lot due to more queries and higher computing overhead.
