Description Nico Stöckigt

When switching from one computerroom to another it might take a quite long time. This is probably due to a hardcoded timeout - in this case 1 sec. It figures out that, when leaving a computerroom, for each computer in the room, whether or not it's online, the connection is closed but in case there is no connection it is waited until the configured timeout. So for each offline computer it took at least 1 sec which can accumulate to a decent amount of time to wait.

Wouldn't it be better if the "shutdown" is done in parallel rather then serial or at least offline computers are just skipped?

Does this apply to Veyon as well? Then please change the component.
