Hey Bruce. Sorry to bother you.

I decided to try getting squeak cog spur to load. But im getting a segmentation fault. I've tried multiple versions of the VM and no luck. Run into this issue?

I'm assuming the CPU isn't enough for it. You have ideas on how I could optimize it? I may end up having to use the c++ original smalltalk-80 baremetal that came out recently...

(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.
