>If the app runs faster on a local machine then yes, something in the network environment is slowing down the networked version. But there are many possible causes, not just AV. If you say "it's probably AV" but it actually isn't you'll lose credibility. I'd just tell them it's something in the networked environment, and get their IT support to solve the issue.

I moved the app to the local drive and it is considerably faster. There are two users from different PCs and both experience the problem. I asked them to shut down Windows 10 Defender, on one PC, and it didn't improve the speed.
Now IT is doing some testing of the network. I think the last I have heard is the IT is testing something (I simply forgot the term, not Pinging but another term). It shows that the call from PC to the server goes though some many "servers" or switches. Anyway, they are finally agreeing to test their end instead of blaming the app. The app actually has been working without changes and without problems for a long time. The problem started at the start of the year (approximately).
