Optimize large data manipulation

I came across a post by @AndersDeleuran on the forum (link provided) that suggested a solution, but it didn’t work as the computational time was even longer than using the standard GH components.

I’m unclear what you tried, but it might be as simple as wrapping the output in the Grasshopper point type:

Grasshopper Performance - Scripting Slower Than Native Components?

Specifically for GHPython, you can usually achieve considerable speed boosts on large inputs by not using type hints or the implicit Grasshopper cycle functionality (i.e. set the access type to List if you’re operating on a list and implement the loop yourself), and on large outputs by wrapping the data in appropriate Grasshopper types: [2021-04-29 09_09_17-Grasshopper Python Script Editor] Mesh Point Remap - multiThreadTest-minimumViableFile_GHPythonFixes_00.gh (1.6 MB) See this old thread…
