The nature of our office is that we have thousands of small csv files per site (10,000 -> 100,000) in folder like structures. When users add multiple sites, it seems that SharePoint sync just doesn't want to work well. Many have trouble keeping up, from 3rd Gen i5 to 8th gen i5s, all with 8gb of ram.
Is there any best practices that will allow users to have a better experience? currently we have them unlink sites they are not using and add the ones they need, But with dozens of sites - this is time consuming. The operation on the files cannot be done through the online interface unfortunately.
The users do not require may files to be synced at all, maybe 10's of files. But it just takes so long to add sites and remove them.
Is there any suggestions on handling sites synced with many files?
