Hi Stéphane, Thanks for your feedback. I agree that the usefulness of these results is limited. However, if we (Object Guild) want to make a case for energy efficiency, it can help if the language itself can be shown to be efficient as well. For now, I think the efficiency will need to come from a good object design. Kind regards, Jonathan van Alteren Founding Member | Object Guild B.V.

The problem is that what do you measure. When you move computation from the CPU to a GPU for example does it consume less or more. I think that such analyses are totally stupid. Is a fast execution consume less? I have serious doubts about it. Now if we measure how fast we drain a battery because of polling vs event based then this is different.

Hi all,
I am interested in energy efficiency metrics for Pharo (version >=8). Just now, I came across this research and related GitHub project:
⢠https://sites.google.com/view/energy-efficiency-languages ⢠https://github.com/greensoftwarelab/Energy-Languages
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?
Kind regards,
