Benchmarking your Mobile App with Rooted Android Private Devices and AWS Device Farm | Front-End Web & Mobile
Article Summary
AWS Device Farm now supports rooted Android devices, unlocking granular performance benchmarking that was previously impossible at scale.
Nikhil Dabhade, Principal Solutions Engineer at AWS Mobile, explains how rooted devices enable CPU clock locking and precise microbenchmarking. This is part one of a two-part series on identifying performance bottlenecks in mobile apps.
Key Takeaways
- Rooted devices allow CPU clock locking for stable, repeatable benchmark results
- Custom mode execution uses Testspec yaml files to configure test environments
- Dynamic device pools with labels improve availability across multiple device instances
- lockClocks.sh script ensures fixed CPU frequency during benchmark loops
- Private rooted devices are exclusive to your account, shareable across AWS accounts
Critical Insight
Rooted Android devices on AWS Device Farm eliminate the need to maintain your own fleet while enabling the precise CPU control required for reliable performance benchmarking.
