Performance spike on generator

[Jake]

We're currently working on a complete dynamic example scene (covering more or less exactly your scenario) and some optimizations and improvements in that department. This will be part of our next update release (after the "hotfix" 2.0.4 submitted this week).

But the delay looks quite long, did you tried to optimize extrusion settings? E.g. disable extrusion's optimize as it optimizes vertex count, not performance. Also Caps are quite costly due to poly2tri triangulation.
