## bonnie-1.0 – performance test of filesystem I/O

## Description

    Bonnie: Filesystem Benchmark Program

    Bonnie tests the speed of file I/O using standard C library calls.
    It does reads and writes of blocks, testing for the limit of sustained
    data rate (usually limited by the drive or controller) and updates on
    a file (better simulating normal operating conditions and quite dependent
    on drive and OS optimisations).
    The per character read and write tests are generally limited by CPU speed
    only on current generation hardware. It takes some 35 SPECint92 to read
    or write a file at a rate of 1MB/s using getc() and putc().
    The seek tests are dependent on the buffer cache size, since the fraction
    of disk blocks that fits into the buffer cache will be found without any
    disk operation and will contribute zero seek time readings. I.e. if the
    buffer cache is 16MB and the Bonnie test file is 32MB in size, then the
    seek time will come out as half its real value. The seek time includes
    rotational delay, and will thus always come out higher than specified for
    a drive.
