Question on scan optimization and UUIDs used


I read on the documentation that some scan configs, such as ‘Full and Fast’ are optimized from previous scans. I am wondering how this is accomplished. Is the optimization tailored to a particular device or as a whole? Either way, can somebody please explain a bit more how that works?

My other question is on the UUIDs that are used for both scan configs and scanner types. Are these UUIDs the same for every user? I am automating certain tasks and it would be computationally easier to simply provide the IDs than have to filter them out from ‘<get_configs/>’.
