Thank you for sending us a video recording.
It seems that the communication between you and our web services is extremely slow. All slow downs, you experience, are at the moments when the Telerik Control Panel is communicating with any of our web services (for example when the splash screen seems to be "frozen", the Control Panel is retrieving some metadata that is needed for it to be run). These slow downs are really strange, because the transferred amount of data in these cases is very small.
Is the process of downloading a product also so slow (after downloading has started)?
As an idea, is it possible that you have installed some traffic analyzer or virus protection software on your computer or private network, that could cause the delay? I would suggest you examining your system and network with your system administrator in order to find what could cause the slow down in sending\retrieving information.
Please let me know if you need further assistance.
