Hello
you should clearify the following questions

Which part of the "HowTo Optimise" do you use and how?
What is the load on your system as of CPU power used?
Have you checked the upstream connection or forwarders used?
Do you use DNSSEC? What kind of data do you use for testing?

Without this no one will be able to tell why your system max out at 3600qps.
