    Hi I need to do some I/O benchmarking on one of our LPARs. I used dd and ndisk. But I'd like to know how ndisk works, or what exactly it is that it does.

    This is because dd and ndisk give good numbers in throughput, but we still have issues with the app writing to the disk.

    So if anybody has any insight on ndisk (nstress), I would much appreciate it.

    Tks.
