I measured the loading time of iClone 7 with my new DELL desktop with iCore 9 and Gforce 2060 graphic.
Time for loading iClone 7 is acceptable to me, since it only does once in a while.

With my project, there is a task at 75% of the progress bar that takes a long time.
At 96% of the progress bar, there is also the 'save undo-redo' data, that also takes up a lot of time.
Kept in mind that, I already cleared out all temporary files of the computer as recommended by iClone 7 tech. support.
You can find all the time length in the following video
But the strangest thing is the deletion of an object such as the standard actor Heidi. With a project containing a lot of objects (and a lot of triangles[faces]), it takes an 'unreasonably long' time to delete and undo.
There is not much very useful comment from iClone 7 technical support 
The following is the video link, I hope it is embedded. I used the Insert Video function of this forum
