It seems that some DNS requests are done every second:
erigontech/erigon#6876 (comment)

Is it possible to optimize it? Probably it's something related to announcement period?

Yes it is very likely due to announce failures, maybe some of those hosts aren't resolving, in which case it will occur once a minute until it does. One solution might be to wait for longer on DNS failure if that's the case. But also if you are running many simultaneous torrents like I suspect you are, the DNS lookups should be shared anyway. I also answered in erigontech/erigon#6876 (comment) by accident, everything there also applies.
