Hi Joseph,

see below.

It's ok as long you don't use to big a display size.
1920x1080 works well, even with the VectorGrahics package
(as long you use the plugin).

With one 3840x2160 monitor (or TV) you can watch it drawing
windows on X11. The Linux frame-buffer driver (thanks again Ken)
seems to be a bit faster. AFIK X11 uses the frame-buffer on Raspbian,
therefore it's no surprise that another layer of indirection
just makes it slower.
It gives you this nice vintage feeling
described here:
https://www.righto.com/2017/10/the-xerox-alto-smalltalk-and-rewriting.html

'the team described performance as between "majestic" and "glacial"'


I also tried two 3840x2160 in portrait mode.
Graphics performance is somewhere between glacial
and tectonic, but -- hey -- it works.

All of this was done with 64-bit kernel
and a 32bit user-space.

I presume all if this would be much faster,
if the VM used OpenVG
(http://www.khronos.org/files/openvg-quick-reference-card.pdf)


Just my 0.01€,

Gerald

(i.e. it's very indirect) Cuis input handling does not feel as fluid to me as a Squeak image. This is one area I suspect Squeak has put a bit more effort into than we have to date. I feel it even on relatively snappy multi-GHz, multi-core machines and it does start to get painful on single-core 1GHz ARM boards if you do much beyond just typing.

I'm using the squeak VM that is listed in the install instructions, and I've also used the one that's built into the "Cuis university" package. I moved the wireless keyboard receiver to the front of my computer and it helped. But I get slight hiccups with input very rarely now. I never got it in official squeak packages (v5.3). It might be my computer as its aged as you can tell from what processor family I am quoting.
