Ok, will test.

Er, how does one run a Go profiling?

It looks like making those changes has sharply curtailed the memory usage; it's now about 125-148MB, although it goes up and down.

At the moment, each dnsdist frontend is taking 5.7-6.6% of CPU, while each dnscollector backend is taking 3.0-3.7%. With 10 of each, that adds up to a lot. Filebeat is...

Running 10 dnsdists and dnscollectors uses 3.89GB (12%), so setting buffers to 4096 and commenting out the transforms really helped. Running 5 dnsdists and dnscollectors uses 3.32GB (11%), so not...

Oh, there are definitely errors: ``` $ journalctl -S '20 seconds ago' -u dnscollector@backend1 -o json | jq -r .MESSAGE ERROR: 2024/09/15 22:58:02.848611 worker - [tap] dnstap - worker[dnstap-processor] buffer...
