PowerDNS can fork the process as many times as you configure using the distributor-threads option.
The good thing is the process remains running and kept running by PowerDNS's guardian so I think it will be more limited by your process than by PowerDNS :) Re: Peter van Dijk Thank you for that, I will check it out :) - right now I also read the openvpn ipp.txt file every time it changes to give vpn clients their own hostname so the pipe backend gives a bit more flexibility, but will definitely check out the remotebackend!
