We have two users accessing the QBD file on a server. Up until a week ago, we had mild performance issues with the opening and closing of the QBD app on the clients. Starting last week, we now have literally multiple minutes long pauses when opening the program and certain windows. By using ProcMon I can see that the program is scanning all (or very many) of the folders in Attach\Company\Txn when the app opens and when certain windows open. We have about 9000 items in that folder. If we run the program on the server, the performance issues are mostly gone. I think it is due to the speed of opening and closing 9000 network connections vs local file queries.

I built an entirely new server, copied the DB over, built a new client laptop. All with clean installs of Windows 11 and Windows Server. I can immediately reproduce the issue on the new server / client.

We were on 2023 and upgraded to 2024 with no change in behavior.

I have no idea what changed over the last week and with all new setup it shouldn't be relevant. I have everything on wired gigabit Ethernet all connected to same switch.

Any suggestions or ideas?
