MicrosoftLearn How OneDrive Sync Works With Office 2016
For years, you have been able to sync your OneDrive (and SharePoint) documents to your PC, which lets you work on the go while still being able to collaborate with others in Office. This integration ...
Along a similar line... I'm looking for information - or better yet: if there are any detailed lab/test results - regarding the throughput and bandwidth usage of SharePoint Online/OneDrive file sync. What is the effect on WAN performance when a file is updated. For a setup of, say, 100+ workstations at an office location (on a LAN) that are sync'ing to SPO/OneDrive libraries, when SPO/OneDrive is implemented as a replacement for network shared drives: I'm particularly interested in what happens as one file is updated, what does the traffic look like when that file is then sync'd back down to all of the "subscribers". What is the difference (network performance data and user experience) when the file updated is pushed to clients. Then we would like to know what are the possible considerations for maximizing WAN and LAN performance.
Hi Daniel, I do not have a specific answer for you however when you use OneDrive Sync on Demand there wil be no traffic generated unless you have synced the file already. Not everybody will sync the file so the traffic will be user-by-user and only for those who have synced the file.
What are you worry about?

Hi Hans,
I'm aware of Files OnDemand, but that is not what I'm asking about.
I'm asking specifically about the traffic for files that are stored on users' computers. They need to have some set of files sync'd locally, as they are in a location where internet connectivity is not that great. They will only use Files On Demand for files/folders they don't need to access regularly; but for files they already have sync'd locally, I want to know what is the WAN traffic/load when an updated file is then pushed to clients.
What's to worry about? user experience. There are some 200+ users (~300 devices) in a location with only ok Internet connectivity.
The benchmark user experience we would like to match is that of network shared drive access, which is: no lag time for access/update. Locally sync'd files have better experience, of course, but Files on Demand would have worse experience - due to waiting for file to download over WAN. Bad perception may end up with users rejecting OneDrive sync. We want to implement OneDrive sync, for purposes of business continuity, corporate document management (access by the rest of the organization, etc.).
I'm really curious to see if there are any engineering studies that have been shared and deeper description of the sync client behaviour. I have already been pointed to the Network utilization planning doc
One thing you'll be disappointed to learn Daniel TSHIN is that unless something has changed since I posted this above several months ago, we've found that even when files are sync'd locally on your PC, Office will still open the file from OneDrive/SharePoint/Internet. So in the cases where you are in a poorly connected location, you wait a long time for it to open and close/save.
We've never been able to get an answer on why it behaves this way - we had hoped that it would be more like Outlook & cached mode.
Hi Adrian Hyde, this is not we're experiencing.
Generally OneDrive NGSC behaves as expected for most of my users.
Today I experienced the opposite of what you're saying.
One group of users quarterly creates a document (for board of directors) where many people contribute to. Unfortunately this Word documents gets rather large very quickly, > 100MB due to a lot of images over 100 - 200 pages.
Word Online can no longer open this document size, and users rely heavily on Word 2016 with OneDrive NGSC to sync changes to file. With Automatic AutoSave you can quickly expect OneDrive NGSC to fail, as 5-10 users constantly upload and download over 100mb with that document.
I'm currently in a situation, where the CEO cannot open the Online Version of that file, and Word 2016 constantly opens some cached version that has a few merging errors. I've tried to delete everything offline from that document library, but Word still does not open the proper (most up to date) online version.
