Hi, Wouter Thanks a lot for your suggestion! The machine is an Intel dual-core CPU. I'll try to increase num-threads and see if it works. About the queries I send. Yes, I use the same datafile and send the same queries in both Unbound and Bind cases. But actually I don't know what kind of queries list is the best and how to generate a good one. So I just use a long list of website names. :( And I configured the machine to forward all queries to the up level DNS server.
