Try replacing the Array with a ByteArray and see if their is any performance improvement.

Very cool. I would not volunteer to refactor that :-D

It's tricky to get high performance GameOfLife in Squeak.
Here is a morph I worked on. I use an array as data structure.
Each cell is an integer. 
Neighbouring cells alive are 0 to 8 and alive cell are 10 + neighbours.

It gets a decent framerate.

Best,
Karl
