Ok. The cog version from opensmalltalk is the fastest.

One thing you can try is to evaluate

          Preferences slowMachine

This disables some things that are nice to have, but it gives better 
response on a slow machine. After that, do

         self runningWorld color: Color veryLightGray; hideTaskbar

to remove the expensive taskbar, and for a more tolerable background 
color. You might still prefer to enable syntax highlighting:

         Preferences enable: #syntaxHighlightingAsYouType

Additionally, this might further improve performance:

         Preferences disable: #subPixelRenderColorFonts

Besides, 512mb ram is less than ideal. Please check how much ram you 
have free when starting cuis. Perhaps we can help reduce it a bit if needed.

I never used a RasPI zero, but I find Cuis usable on a RasPI3B, if the 
cog VM is used. I hope this helps.
