Retrieve your Active Directory objects to a variable first, then send it down the pipeline using the variable. This method is easy to implement in your code without lots of configuration changes in your Active Directory environment. It works because writing the objects to a variable is very fast so your Get-ADUser and Get-ADComputer cmdlets can quickly write all object to the variable and request the next page until all object are received.
