Desktop client on Windows 10, slowing down Windows Explorer

Hello
When the client is synchronising, the Windows explorer is slowed dramatically while creating a folder or modifying its name. It can take 10-20 seconds before returning control to the user.
I have 10s of GB (files, photos).
In order to be able to work, I need to suspend the synchronisation.
Is there a way to improve it, or at least to suspend programmatically, periodically, or temporarily the synchro?
Thanks & regards
Alexandre
