When the users of a file format or reader are many concurrent AI agents rather than one human, single-reader latency tables undersell the difference. A clearer headline is capacity: on one fixed machine, raise the number of concurrent agents N (1, 2, 4 … 96) running the same fixed primitive-op sequence (open, value-at, window, whole read) until each format breaks either a latency target (p95 per-op over a stated budget; report two budgets so the choice is visible) or memory (total PSS over ~90% of RAM, any OOM or swap). Report max N per format at each limit, plus CPU-s, PSS, disk bytes read and storage per agent at that N. Size the machine so the heavier format actually reaches its limit inside it; estimate per-agent memory from a small N=4 run first. Use PSS, not RSS (shared pages counted once), separate cold and warm passes, and never extrapolate past the measured N without labelling it an estimate.
