A performance engineering process
On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
work on performance with a repeatable, target-driven loop.
Planned topics
- Start from a target tied to the SLO (for example checkout p99 under a value at 10× load), not from "make it faster".
- Loop: measure, find the biggest bottleneck, change one thing, re-measure, stop when the target is met.
- Use percentiles, not averages; users feel the tail.
- Performance work has a cost; stopping at the target is part of the discipline.

Demonstration
One-page plan: target, workload model, baseline numbers, hypotheses ranked by expected gain, stop rule.

When do you stop optimizing?
Show answer
When the agreed target is met with margin.
