  2. Benchmarking start with default configuration if you didn't change the configuration.


  • Default configuration
    • TARGET: target='/data' (Internal Storage)
    • FILE SIZE: read file size='32MB', write file size='2MB'
    • BUFFER SIZE: sequential buffer size='256KB', random buffer size='4KB'


  • Notice
    • You can see warning dialog when the file system of your target storage can't support DIRECT_IO(e.g. YAFFS).
      • In this case, benchmarking takes long time
        and requires '/sdcard' that has free space for purging cache.
    • You can see error dialog when target storage of your device has not enough free space,
      • Please change the benchmarking file size at setting tab.
