Protection can add startup work. Measure cold launch, return from background and readiness for the first sensitive operation separately.
Evaluation approach
Inspect main-thread work, SDK order and initial network dependencies. Reduce unnecessary synchronous work while preserving sensitive-flow readiness requirements.
Application example
An informational first screen can appear while preparation continues, with payment access withheld until verification completes.
Limits and considerations
Deferring all security initialization for speed can create a risk window.
The first visible screen is not the whole experience
An application may appear before its security component is ready. Measure first interaction and first sensitive-action availability separately. Moving work to the background may simply shift its cost.
Include cold starts, first launch after an update and return with an existing session. Test low-capacity devices. Define readiness indicators and error paths so users do not face an unexplained wait.
Checks and decisions
- Define readiness conditions
- Measure cold starts
- Test first-operation races
Design startup performance and security within the same lifecycle.
