-- Perf-test hub config: mirrors the production hub config in the repo root
-- (hub.lua / instance.lua). The launch script overrides hub.instance.config
-- and the effective concurrency (--corelimit=128) via CLI to simulate an
-- r5n.32xlarge box so the default auto-picks match what prod sees there.
