Processing time issue in SR17

Grasshopper

Hi, after recently moving from Rhino 8 SR15 to SR17, we’ve noticed a fairly significant uptick in processing time for some processes. See the screenshots below - the example computation is a fairly simple extrusion of around 12500 polylines. We’ve run this on both SR15 and SR17 on machines of the same spec. This extrude component takes about 400ms to run in R8 SR15, but then takes 20.1s to run in R8 SR17 - roughly 50x increase in time!

Not sure if there is an immediate solve now, but can this be looked at for the next release? We’re holding back on rolling out SR17 for now.

Cheers,
Andy

Hi Andy -

Thanks. I’ve put this on the list as RH-86877 Grasshopper: Regression: Exponential Increase in Processing Time

Thank you!

Hi Andy -
Apparently this was changed because an earlier update of the component broke Grasshopper definitions that were created in Rhino 7. For older definitions to remain compatible in Rhino 8, this component needs to output surfaces and not extrusion objects. A new component that creates extrusion objects could be added in Rhino 9.
