What happens when a defrag is running while the server is under high I/O load.

Would the defrag simply slow down or would the application using the hard disk be hindered?

    Hi elmoredaniel,

    little bit of both, you are best off doing it in a quiet period rather than put the extra strain on it

    > little bit of both
    Can you be more specific, would the process priority settings effect this

    > you are best off doing it in a quiet period rather than put the extra strain on it
    Obviously, but this is not an option.

    well you run defrag you are going to smash your system processes not matter what you do, the machine may well handle it depending on your RAM and processor speed but i find it does drain a lot of resources    the server will prioritise and do what it thinks is best but you will slow down your machine.....
