Investigate the Request Path Before Reaching for a Cache
A practical guide for locating bottlenecks and defining a measurable validation plan before proposing a performance fix.
Define the path that matters
Choose a representative user-visible path and state the conditions under which it feels slow. This keeps the investigation anchored to an experience, not a vague label.
Segment before optimizing
Separate browser work, network time, application work, and dependency calls. A trace is useful when it changes the next question, not when it simply adds detail.
Validate one decision at a time
Compare the same path under the same conditions, then record what changed. This is a general investigation framework, not a claim about a measured client result.
