Hi!
Processing time
My apologies, I’ve forgotten that this tool is available only for Windows.
Speaking about the processing time I can recommend you article Hardware components usage when processing with Pix4D which will give you more insight on which hardware component is used during certain processing steps. More information on each component’s task you can find here. From the Quality Report, I can see that GPU was not detected, that is an additional reason why the processing goes so slow. Read more in:
Project
From the Quality Report, I can see that the main problem of your dataset is the number of matches between pictures which is too low. Please see the Figure 5. You would need to increase the overlap between images to prevent your outputs from having holes.
Sketchup
Please have a look at the post: Importing DSM, DTM, and/or contours into SketchUp
