BOT Running very slow on Internet Explorer

I have exactly the same behavior at the the same exercise (Download monthly report). In the beginning it runs fine. In my case I used an example that had no reports available up to July. Then at July it finds a report, downloads it and every action after that is slow and takes roughly 30 seconds.

Weird thing is, if you Stop (F12) the workflow during execution and try to run it again from the beginning, it will then be slow from the beginning (so also Jan - June in my example). To reset the whole machine, you then first need to Close Internet Explorer AND UiPath Studio.

Could there be some bug with the For Each loop or the activities inside the Else part?

WaitForReady=None seems to speed up again, but Interactive and Complete sometimes necessary (e.g. Vendorinformation in the training environment).
