Performance Center is the best option if your testers are not in the site as the PC server

* Once PC is integrated with ALM QC you can only apply ALM(QC) patches if the PC has the same patch available
* In most case if a patch is apply to the ALM server All PC servers/machines must be patched to the same level
* Performance will require at 4-5 additional servers/machines and depending on your testing need many more machines.
