Long Roon Remote Startup Times on Android Devices

Being a Roon user since almost 2 years, I wanted to share a little inconvenience with you and hear about your experiences:
I am using Android devices, be it a nexus 9, fire kindle hd 10 or a Google Pixel XL to control my Roon Core on a NUC5i3 with Win10.

Regardless of which remote device I use, i need to wait approx. 10sec until roon is up and running on my remote device. First, I have to wait around 3 seconds until the Roon splash screen appears then another approx. 7 seconds until i have access to the roon remote interface for playing music.

Are these typical loading times? If no:
What can be done to improve these startup times?
