System Slowness after upgrading to X Endpoint from Local Endpoint

We have recently upgraded from Local Endpoint to Cloud X Endpoint and have had user report of a lot of slowness issues. I have been able to see it happen and it maxes out there hard drive dragging there system to a crall. Is there any way to have the updater only update when the system is idle for a long time or have the updater run in a less aggressive mode?
