It includes an fsync() in the timing measurement when writing the file, and does a posix_fadvise() before reading it back (both intended to make sure that the I/O is going to the device under test rather than just hitting cache memory). You can do the same things in a 'dd'-based test, but it requires a few additional steps. _______________________________________________ support mailing list support@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/support
