2 min readAn original planning guide. Use the linked primary documentation for platform details and the supported procedure for your environment.
Identify the request
Record the exact URL, time, user state, and cache context. Separate the document request from later asset requests.
Inspect timing stages
Use approved browser or server diagnostics to distinguish connection work, request waiting, and relevant backend processing evidence.
Compare a useful control
Check a static resource, another route, or another region only when it answers a specific question. Avoid changing several conditions at once.
Assign the next test
State which layer the evidence suggests and what observation would confirm it. Keep application, hosting, DNS, and external dependency explanations separate.
Worked scenario
See the plan in practice.
A dynamic account page waits longer than a static image. That comparison suggests examining request processing, while still checking connection and cache differences.

Your acceptance checklist
Request exact- Stages compared
- Hypothesis testable
Use these checks to identify gaps in your first-response investigation note. Assign an owner to any unresolved item before the next dependent step.
The terms behind the task
- Time to First ByteTTFB measures the time from a request's start until the first byte of its response arrives.
- LatencyThe delay between initiating an operation and receiving a response or result.
- Application serverSoftware that runs application logic and generates responses using code, data, or other services.
