After reading the information in the SWX Help and this great information from Cati I decided to do some test with this improvement.
Both Parts I used for the test have the same history.
Create in SWX 2013.
Update with FVUT to SWX 2019 SP 3.
Test (before and after update thread) was done with SWX 2019 SP5 with a local copy of the parts.
The increase of the rebuild time about 246 % in the second part was really a shock for me.
Did anybody made the same experience?
Is it possible the increase is caused from a bad setting in my client?
Cam you share both the parts and the exact steps to update the cosmetic thread?
Not that I can do anything with it, since I am still on SW 2018 Sp5, but I imagine that someone will want these to at least comment on the why...
