Hi, Rhino 3.9 is the last version that is not supported no more. @eirannejad would it be possible to increate the version from 3.9.10 to 3.10 ? [image]

Does Grasshopper and Rhino Python are different or not? I am wondering if Grasshopper .NET interface has overhead on its own?

[image] Petras_Vestartas: I am wondering if Grasshopper .NET interface has overhead on its own? That probably depends on what you’re referring to. But there certainly are costs associated with inputting/outputting/casting, but those can be largely negated (at least in GhPython, but I hope tho…

This thread is so interesting and answers some of the questions I had for some time now. Thanks @eirannejad and @stevebaer for being so honest. I’m not gonna lie, it’s a bummer that Python3 is slower when dealing with RhinoCommon and thus rhinoscriptsyntax. It’s nice to be able to finally use some…

[image] diff-arch: Python3 comes in at 1.0s vs 259ms for IronPython for the same code from my latest Corona-19 isolation experiment. That’s what a 74.1% performance increase/decrease? Just out of curiosity/adding data points, how does GhPython perform with the same code?

[image] AndersDeleuran: Just out of curiosity/adding data points, how does GhPython perform with the same code? Do you mean using the Grasshopper Python API, instead of RhinoCommon, or the legacy GHPython component?

Here you go: [Screenshot 2025-03-27 at 10.48.43] Exactly the same code, the same inputs and outputs, and internal printing turned of.

Wow… @stevebaer How impossible would it be to start an open-spource CPython ‘RhinoCommon-like’ project with contributors from outside McNeel? At least to exchange data from Rhino C++ to CPython. I am quite sure you did pybind11 and nanobind wrappers. It would be good to restart this discussion. I…

Exactly what I meant here: [image] Rhino Python 3.10 - Please support it! Scripting Additionally, performance-wise, the Python3 editor even cannot compete with the IronPython one: [image] Even I use concurrent.future for multi-threading, it is still much slower than th…

Exactly what I did for IG-Mesh Though the issue is you cannot support macOS unless you have a Mac Machine…

I meant running the same code in the legacy GhPython component (also adjusting for input/output cost, if any).
