'Perp Frame' Component Runs Slow in RH8 / GH

Grasshopper
1

Hello all,

I’m having an issue with the perp frame component in Grasshopper, Rhino 8. The component runs super slow in Rhino 8. I did a comparison with the same curve, same components, in Rhino 7 it seems to be reasonable. (screenshot attached, showing rhino 8 runs almost 10 min vs rhino 7 about 45 seconds)

Initially I thought it could be caused by the changing from .Net Framework to .Net Core, but after testing in both modes using the setDotNetRuntime Command, it seems in RH8 there is not much difference in both modes.

Here is the gh file, the curve should be internalised already.
testFile.gh (307.2 KB)

And both of the RH7 and 8 system info just in case
rhino7 sysinfo.txt (2.5 KB)
rhino8 sysinfo.txt (3.3 KB)

I have other ways to workaround and avoid using that component but just trying to figure out why there is this huge processing time defference between rhino 7 and 8.

Thanks in advanced.

I’m experiencing the very same as you, and it’s weird because Evaluate Curve + Plane Normal (which outputs very similar stuff as Perp Frame but without accounting for torsion) takes just a few ms to compute
