Eweka takes ~1.5–2 s per XOVER command whatever its size. One connection on recent a.b.boneless: 9–15k lines/s in chunks of 25k, ~20k in 50k, ~30k in 100k–200k. Four connections at once: 15k each at 50k, 22k each at 100k (the same as one connection alone at that moment): connections don't slow each other. CHUNK_ARTICLES defaults to 100k; edge:node posts a batch every --batch-articles (500k) instead of every N chunks. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
