GameBench will add around 0.9MB to your Android .apk and 0.6MB to your iOS .ipa (or just 0.3MB if you only build arm64).
GameBench performs very little dynamic allocation and it’s impact on RAM usage is reasonably constant at around ~200KB on both iOS and Android.
To measure the impact of GameBench on CPU and Power usage we profiled game demos on common devices to measure the difference once GameBench was enabled. Each game demo required no user input and therefore performed the same path each time, each ran a minimum of 3 times and for the same duration each time.

Storage and upload size overhead - 10Kb for 10 mins session
Screenshots can have a significant impact on session data sizes and upload times so GameBench screenshots use lossy JPEG compression to minimize this. For a typical smartphone with a ~3 megapixel screen a full-size capture will be saved at 50% JPEG quality and occupy roughly 100KB of storage. If you need very frequent screenshots we recommend using one of the reduced size capture options which need much less space.
