The M/M/1 queue models a single server with random arrivals and service — a checkout, help desk, or router. The utilization ρ = λ/μ decides everything: as it approaches 1, the average wait and queue length explode toward infinity. This nonlinear blow-up is why systems run at, say, 80% and not 99% capacity.

Governing equation

ρ = \frac{λ}{μ} = \frac{0.7}{1} = 0.70, L = \frac{ρ}{1 - ρ} = 2.33, W = \frac{1}{μ - λ} = 3.33

Reading this result: Moderate load: ρ=0.70. On average L≈2.3 in the system waiting W≈3.3. You are on the steep part of the curve — pushing ρ toward 1 makes waits climb far faster than the extra traffic would suggest.
