Need help with activity monitor. What can I do to increase available ram?

I just learned about Activity monitor and would love some help understanding what I can do to improve my Macbook Pro's performance (see screenshot below). Some questions that I have: 1. Any idea what com.apple.cmio.registerassistantservice is used for? I tried Googling and searching on Reddit to no avail... why is it using 3.44gb of ram?? 2. I know I have lots of Google chrome tabs open and unfortunately, don't think I can do much about that (I have multiple Google accounts that I am using daily). My Macbook Pro currently has 16GB of ram. Would upgrading to 24GB provide a noticeable difference in performance? 3. Any other concerns or callouts based on the Physical memory, memory used, cached files, and Swap used? Over the last week while looking at Activity Monitor, I'm almost always in the yellow/orange zone. https://preview.redd.it/52dmr7srm3ae1.png?width=1676&format=png&auto=webp&s=fdaf2f700337861356a6ad88c9aad793e11c33fd
