The coordinator's event loop was 16.5% busy at ~10 MB/s of compressed XOVER (socket reads, buffers, GC, spool writes; nothing stands out), so one process tops out around 60 MB/s: less than 50 connections bring (~1M articles/s, ~70-86 MB/s). A shard prefetches the ranges with id % n = i - 1 with its own NNTP_CONNECTIONS; only shard 1 plans, merges and settles. Two shards of 5 connections fetched what one of 10 did.
