How do I identify if bind9 is using 4 cores?

[Petr Menšík]

Consult log of bind9 service. It should autodetect 4 cores without any
options, just with plain start of the service.

It should show isc-socket thread for each core:

pstree -t $(pidof named)

I were surprised of my output however, because I have multiple
isc-net-000{1}. My version is bind-9.16.18-1.fc34.x86_64

$ pstree -t $(pidof named)
named─┬─2*[{isc-net-0000}]
      ├─5*[{isc-net-0001}]
      ├─{isc-net-0002}
      ├─{isc-net-0003}
      ├─{isc-socket-0}
      ├─{isc-socket-1}
      ├─{isc-socket-2}
      ├─{isc-socket-3}
      └─{isc-timer}

Are those numbers intentional?
