Hi, I've got vm based unbound and trying to tune unbound perfomance to able process huge loads. For testing I'm using dnsflood utility. (https://github.com/nickwinn/dns-flood)
Server has 16 cores (unbound max-threads also 16) with 6GB of memory. When I perfom flood, ./dnsflood A 10.0.0.10, server simply stops replying: dig @10.0.0.10 google.com ;; Warning: ID mismatch: expected ID 28634, got 48552 ;; Warning: ID mismatch: expected ID 28634, got 41394 ;; Warning: ID mismatch: expected ID 28634, got 62162 ;; Warning: ID mismatch: expected ID 28634, got 25233 ... Trying this https://nlnetlabs.nl/documentation/unbound/howto-optimise/ but that doesn't help. Maybe there is some perfomance tuning of unbound to help process massive loads?
