I met a performance regression for API ‘SUModelCreateFromFile’ between SDK_WIN_x64_2019-0-753_0 and SDK_WIN_x64_2020-0-363.
My machine: win10, visual studio 2019 with release x64
I chose polyline3d.skp to profile the performance based on the same sample code(SDK_WIN_x64_2019-0-753_0.zip (6.3 MB) ).
On SDK_WIN_x64_2019-0-753_0, ‘SUModelCreateFromFile’ cost is 8.4%:
On SDK_WIN_x64_2020-0-363, ‘SUModelCreateFromFile’ cost is 63.64%:
