Re: ADDM advices Oracle's application logic

iozone results in Ops per sec.:

        File size set to 1048576 KB
        SYNC Mode.
        OPS Mode. Output is in operations per second.
        Command line used: iozone -s 1G -o -O –a
        Time Resolution = 0.000001 seconds.
        Processor cache size set to 1024 Kbytes.
        Processor cache line size set to 32 bytes.
        File stride size set to 17 * record size.

Same results, now IO (kB) per sec:

        File size set to 1048576 KB
        SYNC Mode.
        Command line used: iozone -s 1G -o –a
        Output is in Kbytes/sec
        Time Resolution = 0.000001 seconds.
        Processor cache size set to 1024 Kbytes.
        Processor cache line size set to 32 bytes.
        File stride size set to 17 * record size.

Actually, quite bad in writes... 4555 kBytes/sec?!?
