Interactive renders when local rendering in client-server mode feels slow

When connected to remote machine that is not on LAN, even local rendering feels slow - as if every interactive frame is sending/receiving something over network. Does anyone else notice it as well?

Which OS ? Which version ?

6.2.0 client is macos and server is linux, but the OS should not matter.

It’s been a while since I’ve looked at the view proxy code, but since you’ve worked with progress and abort recently, you might want to check that vtkSMViewProxy::InteractiveRender() is not unnecessarily calling PrepareProgress() and CleanupPendingProgress() as that will force a server communication as far as i can recall.

Well, version check indeed a reason for my question. Nothing in abort check is present in 6.2.0.
