💬 Discussion 13 — What Your p99 Curve Actually Revealed (20 pts)

Before you ran your load test this week, you probably had a guess about where your capstone would break — "it'll be the GPU," "it'll be the database," "it'll be fine until at least 50 users." Now you have real numbers. Post a response covering:

- What you assumed your bottleneck would be before load testing, and why.
- What your p99 latency curve actually showed — where the knee appeared, and at what load level.
- What the real bottleneck turned out to be once you diagnosed it (batching, model size, resource limits, network, something else), and how that compared to your assumption.
- One thing you'd do differently in your capstone's architecture or configuration as a result.

Then respond to at least two classmates — look specifically for cases where someone's assumed bottleneck was wrong, and ask what evidence convinced them of the real one.
