Memory Issue in Grasshopper: Rhino 6 vs. Rhino 7

I see that the Rhino 7 runtime is still longer than Rhino 6 but it’s only an increase of ~35%.

This does appear to be a general case for “large” GHPython computations. Where Rhino 6 was slightly slower than Rhino 5, and Rhino 7 is noticeably slower than Rhino 6:

Newer IronPythons iterate more slowly?

It might also be worth noting that GHPython performance appears to have dropped in general, at least in cases with many iterations/large computations. It’s a pattern I starting noticing when Rhino 6 launched, where my Rhino 5 definitions developed using GHPython “felt” slower on Rhino 6. Here’s a super simple, but consistent, example.
