Thanks. I know SOM and Smalltalk pretty well and have implemented several VMs myself (see https://github.com/rochus-keller/Som/ https://github.com/rochus-keller

Thanks. I know SOM and Smalltalk pretty well and have implemented several VMs myself (see https://github.com/rochus-keller/Som/ https://github.com/rochus-keller/Som/ and https://github.com/rochus-keller/Smalltalk/ https://github.com/rochus-keller/Smalltalk/). SOM was originally designed and implemented by Bak and Lund at Aarhus university. It's very well suited for performance experiments and shares with Smalltalk the relevant features. There is an implementation of the Are-we-fast-yet suite for both SOM and Smalltalk.
