Hi all,

I am interested in energy efficiency metrics for Pharo (version >=8). Just now, I came across this research and related GitHub project:

Unfortunately, the paper mentions that Smalltalk was excluded from the results because the (VW) compiler was proprietary :-S However, the GitHub repository does contain Smalltalk code and results, but I haven't been able to evaluate those.

[1] Does anyone here have more information on this topic?


The benchmarks seem to be low-level algorithms. Although that is useful, I think that a better argument for Pharo/Smalltalk efficiency is that a good OO design (e.g. created using responsibility-driven design with behaviorally complete objects) will be a better fit, can be much simpler and will thus be more efficient during development, as well as easier to maintain and evolve.

[2] Has anyone done any research in this area that can quantify this aspect?
