Since I have added new memory to our Dell PowerEdge T710 server certain tasks are taking a lot longer to complete. I upgraded from 6 x 1GB stick or RAM to 2 x 8GB sticks of RAM.

For example when I open up task manager it takes over 10 seconds to display and then when I move across the tabs it says not responding and then takes a couple of minutes to display the next tabs information.
Also a robocopy job takes a lot longer to complete now. I am writing from a NAS to external USB 3.0 drive attached to the T710.
