3DEXPERIENCE NC Tool path Computation progress

Hello, Hope you can overcome COVID-19.
I have a question about 3DEXPERIENCE NC speed.
What are the criteria for 3DEXP NC Tool path computing?
Operation EA? Function? , Part? , Stock ? DB Server? , ENV? , Local PC?
V5 NC (15m00s) to 3DEXP NC (50m00s) Tool path computing process speed difference at the same DATA.
Is there any additional request to help with this question?

Thank you.
