Scrolling in the browser was exactly the test I made. No wait times at all, the screen updates were instantaneous, even the first time, I.e. Cold cache in the little HP.

Notes: based on previous experience I upped the memory for holding images from the default 64 MB to 256 MB. The HP has 2 GB, a Celeron processor, 32 GB SSD. The HP is wired to the router, Gigabit although I'm not sure tha HP uses Gigabit. The Roon Core machine is wifi to the router, but multi AC with Gigabit+ speed, it has an 8 core CPU and 8 GB, I upped the image cache to maximum 256 MB and the cache was well and truly warm. So this is likely the best possible environment for the HP to live in.

But it does show a very minimal user interface machine for Roon. Modern machine, but minimal.

Only problem: I used the 50" TV as a display, and I kept going up to it to swipe, and the stupid thing is not touch...
