NGINX slow_start: Gradual Upstream Ramp-Up Without Plus
by Danila Vershinin, April 22, 2026
NGINX Plus has slow_start to ramp traffic to freshly-live upstream servers from zero to full weight. Open-source NGINX has the struct field but never wired the scheduler. NGINX-MOD ships the missing scheduler logic and this article proves it with runtime measurements from a Rocky Linux VM.
