Measure protection delay through the user's completed task. Keep startup cost, network verification and critical-operation waiting distinct.
Evaluation approach
Measure local checks, evidence generation, network time and server decisions separately. Compare percentiles on representative devices and networks.
Application example
Measure from confirmation tap to final transaction outcome, not just the SDK call duration.
Limits and considerations
One laboratory run does not represent the user population.
Define the measurement boundaries
SDK execution time, network verification time and end-to-end completion answer different questions. Reporting them under one label makes comparisons unreliable.
Review slow-tail latency and device segments alongside averages. Separate cold and warm starts, cache states and network conditions. Show total user cost together with security benefits.
Checks and decisions
- Measure stages separately
- Inspect slow-tail cases
- Record network conditions
Optimize demonstrated bottlenecks before reducing security coverage.
