Bitcoin Core addr gossip is rate-limited right after connection open

Also, I’d expect more than 497 instances of 1,000 entries in ADDR especially when you compare that with the ~1M instances of 1 entry. Especially since we should receive 1,000-entry ADDR message per outbound connection?

This isn’t so unexpected to me. ADDR messages with 1 entry are typically gossip relay of someone’s self-announcement (not necessarily originating from the peer itself), and both inbound and outbound peers can send gossip ADDRs every 30s ( AVG_ADDRESS_BROADCAST_INTERVAL) - we receive a GETADDR answer only once in the lifetime of a connection, and that only with a full outbound peer. Since we don’t make so many new full outbound connections once we have found a stable set of peers (some exceptions such as stale-tip extra outbound every now and then exist) a much higher number of gossip ADDRS makes sense to me.
