Hi,

We are currently running DU40F and one of our batch jobs is taking longer and longer to run. The time taken by the job has increased by two hours over the past month.

We are trying to determine if there is a bottle neck in the filedomains. We know that only specific domains are hit be the process but we need to determine if there domains are getting overloaded and thus the process is running slower because the IO operations are slowing it down. Our domains are stored on 6x9Gb disks in RAID 0+1 on HSZ70 controllers.
We have Checked the CPU load and that is not a problem.


Is there any tools out there to determine this or does anyone have any ideas.

Thanks
Will.
