Queue Capacity & Backpressure Lab
Push producers faster than consumers and watch queues, waits, and drops emerge.
At what queue depth does the consumer tip over?

- Utilization ρ
- 30.0%
- Stable?
- yes
- Mean wait (M/M/1-ish)
- 1.1 ms
- Time to fill queue
- n/a
Arrival below capacity — queue stays bounded.
λ=120 μ=400.0 depth=500
Method
- Deterministic local model of the mechanism — knobs recompute outputs instantly with no network.
- Numbers are teaching approximations, not production capacity guarantees.
