Active OneDrive slows down entire AVD environment

Question

Active OneDrive slows down entire AVD environment

EBrin 25

Our client is using AVD for about 5 weeks in 'production' now. It is a smaller company with about 40 users. We have 6 VM's in AVD (D4s_v5) in use at the moment. We have tried D8s_v5 without any improvement.
We have the following issues:
But we see memory and cpu usage at high levels most of the time with OneDrive at the top of the processes. Every server feels sluggish at the moment. Starting Excel takes about 30-40 seconds, Word about the same time. Opening a Word document takes about 20-25 seconds to open and opening folders from the right (yes only the right pane) in explorer takes about 7-15 seconds per folder.

All those folders are folders from SharePoint document libraries.
It doens't matter if a folder is fully synced with the server or it isn't.

We are using FSlogic with profiles stored on azure.

I was reading a blog of Christian Brinkhoff about almost the same kind of issues but can't really pinpoint the exact cause or find a solution for this issue.

Can you help me out?

@Emiel Brinkman Thanks for posting your query on Microsoft Q&A.
I would need more information to investigate on this:

Make sure that Windows has the latest updates installed, same for OneDrive and FSLogix

Do you use any 3rd party security software on the system?

Do you use any GPOs to force a specific behavior of OneDrive? (e.g. specific sync settings for libraries)

Why do you use ODFC if you store it on the same file share as the profiles? In general, we recommend to keep the FSlogix configuration as simple as possible if there are no specific requirements that make other configs necessary. So, you would use just the profile container for the entire profile.

We also recommend using Azure Files Premium for FSLogix in production.

Are you also running any proxy services that are forcing the traffic to OneDrive to route in a more roundabout way?

- YES! We connect to the libraries through GPO's -> We use the siteID's for that.

Extra information:

We have installed a fresh VM, not an Microsoft image, and a fresh installation of Office.
This seemed to solve the issues but after three days browsing through SharePoint/OneDrive files and folders in the explorer slows down again - 20-30 seconds per click.

@Emiel Brinkman Thanks for sharing the details. I am investigating this. Can you also provide info on:
-What region are the session hosts located in relation to the users?
-Is the FSLogix storage in the same region as the session hosts?-can you try removing those libraries that you sync via GPO, at least temporarily on some systems, to see if the issue still happens?

Hi Karishma!

The users and hosts are located in West-Europe (Netherlands)

FSLogix storage is in the same region.

We will have a look into removing the libraries - it's a production environment so this could be an inssue. Will let you know.

Removing the libraries did not solve these issues.
We do hear some customers complain about slow OneDrive browsing through explorer on local devices. Could a bug in the latest OneDrive client be the cause of all of this?

But we also still see the issue opening Word, Excel, Outlook etc takes about 30 seconds.
I have tested this with two accounts active on a D4s_v5 - so lot of resources available.

And in addition to my last post. When I open Word or Excel from the Desktop (which is synced with OneDrive) it is slow (30+ seconds to start). When I start Word from the startmenu (not synced with OneDrive) it starts in 3-6 seconds.

We have the exact same Issue, every click in onedrive is slow. At best 8 seconds, worst case 30 seconds for every click (folder or file). Other profile folders are fast, so it doenst seem to be related to FS logix profile disk). Only the onedrive folder are slow!

Windows 11 Multisession

FS Logix on Azure Storage

WE only use onedrive at this point for personal storage, not yet for company files.

Recently reinstalled the AVD VM's, seemed ok, after a while Onedrive folder are slow again (rest is fast

Running on E8s_v5 VM's (amount of users doesnt matter for onedrive performance)

Pretty sure this is a bug... unfortunatly it hasnt been fixed for 3 month now..

No update - no solution. A bug that's present for over 5 months now. No solutions from MS, only new OneDrive clients which solved the issues for about 3 minutes.....
We have decided to move from OneDrive/SharePoint storage tot Azure storage.
That works fine. But the client lost all the M365 functions with that.

I have a client who has exactly these symptoms. Too slow browsing in Windows Explorer through the OneDrive folders. Browsing over drive C and mapped network drives works perfectly. Opening a file from OneDrive takes a lot of time.

Using OneDrive client: 24.111.0602.0003 which is the latest at time of writing.

The release notes are simple: We've resolved product issues to improve the reliability and performance of the OneDrive sync app.

Did someone ever find a solution for this? Having the exact same problem with a client of ours. The weird thing is, we have all our other customers still on win10 and they are using OneDrive/ SharePoint without any issues. This client has Win11 and latest the latest FSLogix version installed. I rather find a solution for this then moving them back to Win10.. Is it a West Europe thing maybe?

This solution has worked for us. Folder traversing in the middle File Explorer pane is much quicker <1s whereas it was taking 3-4s each folder. Hope this helps until MS fixes this.

The Windows team has identified a bug on their end that occurs when numerous user sessions accumulate over time leading to these performance delays.

While the OneDrive fix is rolling out, admins on the AVD / VDI machines can manually clean up the sync roots that have accumulated over time, by deleting the child keys under:

"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\SyncRootManager"

Note: We recommend that users are logged off of any active user sessions before this cleanup or that the host is rebooted after the cleanup to ensure that OneDrive correctly re-registers with Windows I hope this will serve as a solution until the fix is released by the end of the year.

We still see that the keys don't get deleted regularly and have much more cpu consumption and much more profile storage consumption since releasing Windows 11.
Is there any news, when Microsoft should have released the fix?

2025-02-17T13:37:00.8366667+00:00

I'm still wondering if there is a new version of OneDrive that addresses this issue. In the meantime, we've implemented a workaround by using a PowerShell script to delete those keys. The script is scheduled to run once a day on each worker.
On our AVD workers, 30-40 users log in throughout the day. Even this number of registry keys is enough to have a small impact on system performance. Our script has improved the situation drastically, but hasn't completely eliminated the issue, of course.

Do you have the fslogix odfc containers enabled?
FOERSTER, Markus 0 Reputation points

2025-02-17T15:45:47.12+00:00

No. Would this change the behavior of the OneDrive client in a way that it consumes fewer CPU resources?
D 111 Reputation points

2025-02-18T07:02:35.2233333+00:00

No. I just ask, because right now we only have migrated the customers with odfc to Windows 11 and wondered maybe that could be the reason. But as you don't use it, we can throw this theory over board.

Answer 1

Hi All,

Firstly anyone get an update on this - we have exactly the same issue.

AVD deployed in April, Multi-Session Windows 11. Latest updates for Windows and 4 pooled avd's with approx 20 users.

Clicking folders in left hand side of explorer is normal but in the main window slow to open subsequent folders. PDf's are fast but word and excel are taking about 10-40 seconds to open.

Disabled AntiVirus and still the same
All others applications are working as normal.

One thing I did note was when in Word or Excel and then navigating to One drive the speed is normal, so seems like a Onedrive/File Explorer issue to me. I also opened cmd prompt and opened files from Onedrive at normal speed.

Regards

Joe

We are experiencing the same issue with one of our AVD customers (West Europe Azure).
Created a new host pool to test a new image, all good.

However after 2-3 days the environment is really slow, most noticable is opening of (larger) PDF-files where Adobe says not responding, these files however are not hosted in the OneDrive.

Answer 3

Stefan Peters 20

Regarding this issue where I posted info on June 28th. Last week we had to rebuild the session hosts for this client for another reason. Updated all apps that are running on the VMs, including OneDrive, M365Apps, Teams New and third party apps like Firefox, Adobe Reader, 7Zip, Notepad++ etc. we noticed that the issues disappeared. Unfortunately we have no clue why, but our customer was very happy with the new session hosts.

We did the same, new hosts which worked fine however after a few days the environment got sluggish again.

If the same happens to your customer could you let everyone know here?

Is it still running smoothly? Are there any changes in version numbers of the OneDrive client or anything else that could have changed? We are still struggeling with the same.

Here also the same issue.

Created new AVD hosts from the image (first fully patched), i think that was quick for acount 4 days, and now it slow again.

Look like if we create an new session host and let 1 user use it, the problem is gone. So Multi session Windows 11 and OneDrive, no good combination so far.

You guys have an solution ?

Hello Erik, your welcome. I hope they can help and allow you to share the solution here.

Answer 4

I made a discovery yesterday about how things were working in our environment. I had undersized the AVD's - we have just 20 users so we setup 2 pools, and incorrectly thought a 2 core, 16gig device would do the trick for each of the 2 servers in the pool. After updating to 4 core models, I also discovered we hadn't enabled the premium disk bursting, so I decided to upgrade the disks to p20's and set t he size to 513gb so I could check the box for bursting, also performed this disk change on our hosted Domain controller that is handing out gpo's and update it from 2c 8gig to 2c 16gig, things are working tons better for everyone so far today. This is something that has worked for this small environment, however the solution for us here was to next time increase the server sizing when deploying.
