    Description

      Here you find my results with Qt3dStudio 2.4 and using a release with debug information build. The example I used for this was the “dynamicelement” example.

      I used vtune for this. It is now free for commercial use.

       

      The question is, why is the hash for all elements created during the find and not directly during creation and then cached? It seems to be that every find the hash is recalculated every time.

       

      Please benchmark the hash functionality with the latest Qt3dStudio version, to verify my results and then fix it when possible. Thanks.
