The performance of that package is slow and when your robot has to run thousands of times, it will soon add up. My advice is you do not use that package at all.
UiPathTeam.SharePoint.Activities
Is not an official UiPath Package. Although the recent version seem to have better documentation than when I last tried it.
I have tried to inform this in different threads:
-
Help understanding sharepoint activity (Get List Item) - Help / Activities - UiPath Community Forum
-
Open Excel workbook from URL - Help - UiPath Community Forum
Instead create a custom PowerShell script which will perform great and you will always know what the code is doing.
