mwiegand b62fc08127 docs(specs): l4d2 cpu pinning — decision record (deferred) ... Investigated whether to hard-pin each srcds instance to a single core within the existing AllowedCPUs=1-7 set. Modern kernels (5.13+) no longer expose kernel.sched_migration_cost_ns or the other classic CFS "laziness" tunables, so a global cheap-fix is unavailable. Decision for now: trust CFS + Nice=-5 + AllowedCPUs=1-7. Per-instance CPUAffinity= remains an opt-in escape hatch in deploy/README.md. Documents the revisit triggers and the preferred implementation path when the time comes. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>		2026-05-09 12:41:40 +02:00
