benchmark: calibrate length of util.diff

RafaelGSS · targos · commit 8ebd4f4434f6 · 2025-08-25T07:07:29.000+02:00
500 + 1000 already cover the curve. 2000 doesn’t add new qualitative insight — it just extends the same curve further down (another ~3–4× slowdown). According to nodejs/performance#186 this benchmark takes one minute to conclude a single run. This should fix it.
