Bloomberg Becomes Browser
summary
Bloomberg embeds Chromium + V8 as the Terminal UI core, replaces a million‑line C++ UI with HTML/JS, and runs across ~350,000 installs handling peaks of ~10 million updates/sec. Engineering builds low‑overhead instrumentation — observable timers (50–100 ns) and metrics like UI‑responsiveness, busyiness and timer‑delay — to attribute main‑thread work across collocated apps, and proposes container timing to measure component paint (LCP proves misleading). The migration runs live to clients and the embedder instrumentation and timing APIs demonstrably cut mystery jank and make performance measurable.
