-- 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.
hub = {
instance = {
baseportnumber = 21000, -- default
limits = {
count = 1100, -- headroom for 1000-module perf runs
memorylimitpercent = 90, -- default: 0 (disabled)
disklimitpercent = 90, -- default: 0 (disabled)

-- provisionthreads / spawnthreads / hub.hydration.threads left unset: defaults
-- (clamp(cpu/8,4,12) / clamp(cpu/8,4,16) / clamp(cpu/8,4,12)) are tuned from
-- 1000-module sweep at 128 vCPU + 30ms latency. Override here only to A/B test.
-- NOTE: hub.instance.config (path to instance lua) is overridden via
-- --hub-instance-config on the CLI. If left here, it would be resolved
-- relative to the hub's CWD at spawn time (NOT this file's dir).
