Pool Exhaustion Simulator
A pool of N TCP sockets, a configurable request burst. The staged experiment sizes — 255, 256, 257, 512, and 1024 — run side by side. Watch when each pool exhausts, how long requests queue, and the tail-latency delta the experiment is measuring.

what the experiment is asking
Chrome 139 is running a staged experiment on the per-profile socket pool: from the long-standing 256 default, branches go to 255 and 257 (to validate that single-port shifts don't have second-order effects), and the bigger pools 512 and 1024 evaluate whether bursty SPA workloads see meaningful tail-latency improvement. The simulator runs the same burst on three sizes locally so the trade-off is intuitive.
