Hi, I have had the exact same experience managing IT for a small company with 15 users.
We have about 450gb of data, 350.00 files that are split up into to 4 libraries but with the biggest one being over 100.000 items. We have 1gb/s fiber connection and our network connection is barely breaking a sweat.
-Save a file.
-Wait a few minutes.
-"Uploading 0kb of 0 kb" (no network utilization)
- Waiting 5 minutes up to 1 hour for a simple document or pdf the be in sync.
Somtimes uploads stall completely. The only way to fix it is for the user to pause/restart onedrive.
From what I can read in the documentation there is a performance penalty above 100k files for Onedrive, and also above 350k files for Sharepoint online libraries.
Is has been a nightmare from the beginning, and we are still not sure if we will be able to stay with O365 for our files or if we have to find another solution.
This problem is not occuring in the regular Onedrive for consumers version.
There is definetly something with sharepoint online that is killing the performance there.
I have tried EVERYTHING (does not matter which OS, Onedrive version, network connection/location, filetypes, firewalls).
I have been in contact with MS support, no luck. No one has even admitted to the problem even existing or have been able to find something wrong in our setup.
Right now we are preparing to clean up our data, and move it into two separate sharepoint sites and also into different libraries. This way I am hoping to make the 100k and 300k file limits respectively.
Also differential sync is rolling out not, this might alleviate the problem a little bit, but i doubt is, since it is not the actual download/upload speed that is the bottleneck.
Hope you find a solution or get out while you can :) Please let me know.
