Adobe Desktop Service Resource Usage on macOS High Sierra

I am on a Macbook Pro, macOS High Sierra, and, looking at the Activity Monitor, I have noticed that Adobe Desktop Service uses more than 220 Mb of memory. This cannot be right!

I am also utterly confused by the plethora of other Adobe processes running, such as CCXProcess, Creative Cloud, Adobe CEF Helper, CCLibrary, Core Sync, Core Sync Helper, AdobeIPCBroker - and these are only the ones that I could spot easily.

What I am trying to find out is:

1. Adobe Desktop Service using so much memory can't be right. Why is it using so much, what is it anyway, can I shut it down and how?

2. Are all the other Adobe processes really necessary? Which ones can I terminate and how?

I know this has been discussed before but I could not find anything recent and what I could find neither made much sense nor were the proposed solutions workable. (I am not a great fan of "try uninstalling, re-install and see if this solves the problem".)

So, if anyone has any useful input ...

Oh, and if someone from Adobe should read this, I would really appreciate an official answer too. After all, I am your customer and I pay good money for your products.

Thanks
