A switchable trace (DATA/perf/trace.on or PERF_TRACE=1) records every request's phases (stat, open, first read, disk vs network wait), browser resource timings, page-turn waits and flow stalls, a cold storage probe, event-loop lag, scans and scraper calls as JSONL. tools/perf-report.js says which phase slow loads spend their time in; tools/perf-bench.js simulates readers. READ_AHEAD (default on) reads an opened chapter's pages, then the next chapter's, into the OS cache so a NAS's cold reads stop reaching the browser.
