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