8.2. File I/O Access Performance
Providing a common baseline for a consistent file access performance on the
application private data storage (/data partition) allows app developers
to set a proper expectation that would help their software design. Device
implementations, depending on the device type, MAY have certain requirements
described in section 2 for the following read
and write operations:
- Sequential write performance. Measured by writing a 256MB file using 10MB write buffer.
- Random write performance. Measured by writing a 256MB file using 4KB write buffer.
- Sequential read performance. Measured by reading a 256MB file using 10MB write buffer.
- Random read performance. Measured by reading a 256MB file using 4KB write buffer.
