Hello

on the OS side you have to assure that unbound get enough resources to  
operate on, so you might need to setup the allowed sizes for socket  
buffers, file handles and the like. For tuning unbound you should  
follow this one:

If there might be problems with many outstanding DNS queries (high  
number of clients) you should have a close look at the libevent section.
