Android app performance diagnosis tool
User-perceived performance variance in mobile apps can occur in unpredictable and sophisticated ways. PerfProbe is a performance diagnosis system that supports automatic detection and systematic diagnosis of intermittent performance problems on mobile platforms. PerfProbe records app and OS-layer runtime information on a mobile device in a lightweight manner to support in-the-wild deployment and applies novel statistical analysis on them to identify critical functions as the source of performance variance and pinpoint relevant resource factors for each critical function to help understand the root cause of performance variance.
