Hi Jeroen, I've built this RC on Oracle Linux 9, and it compiled without any errors or warnings. Configured a test virtual server with 449 primary zones (a mix of small and big, signed and unsigned). NSD 4.9.1 takes 26s to load all the zones (measured over 2 runs). NSD 4.10.0rc1 takes 13s to load them (also measured over 2 runs). Not bad.
