Over the weekend we started noticing that the performance for one of our users was very slow.
No changes were applied to the server when these issues started showing up. We did move one of the drives to a different aggregate on the SAN, but that happened a week before the issues started manifesting. Performance was fine after the migration for the first few days.
Another user shares the machine and he is not having any issues.
This performance impacts everything from just opening to the home screen (which can take up to 20-30 minutes) and jobs running very slowly.
Nothing seems to be competing for resources.
Any thoughts as to what might be causing this issue?
