People on Macrumors immediately saw stable WiFi connects and near-instantenous WiFi re-establishment speeds on laptop wakeup. I wonder what led Apple to develop discoveryd in the first place. With such a project, it seems like there were some important issues to solve with mDNSResponder. Or is it just a mess of a code, peforming well but hard to maintain? Who knows. Maybe discoveryd isn't even dead yet, just in quarantine while they fix it...?
