From the website: It tests specific device properties you do not regularly see tested by other benchmarks, and runs in a set timeframe. It does produce some "final" scores, but as with every benchmark, you should take those with a grain of salt. It is simply not theoretically possible to produce a single number that accurately describes a device's performance. .. note:: This workload relies on the device being rooted """ package = 'eu.chainfire.cfbench' activity = '.MainActivity' run_timeout = 5 * 60 # seconds summary_metrics = ['overall_score'] cfbench_params = ['java_mdflops', 'native_memory_read', 'java_msflops', 'native_disk_read', 'native_score', 'java_efficiency_memory_read', 'native_mips', 'native_mdflops', 'java_score', 'native_memory_write', 'java_memory_write', 'native_mallocs', 'native_msflops', 'java_mips', 'java_efficiency_mdflops', 'overall_score', 'java_memory_read', 'java_efficiency_memory_write', 'java_efficiency_mips', 'java_efficiency_msflops', 'native_disk_write']
