- Batch real-time packet push_events: collect marker data across the packet batch and send a single "new_packets" WebSocket message instead of one per packet. JS handler processes all live→historical conversions before adding new markers to avoid intra-batch conflicts. - Batch RF path station queries: replace N+1 get_latest_packet_for_callsign calls with a single DISTINCT ON query selecting only callsign + lat/lng. - Add read_concurrency: true to streaming_packets_subscribers and :aprsme ETS tables (read-heavy, rarely written). - Remove dead GC code in PacketConsumer (threshold > 1000 unreachable with max batch_size of 100).
