Raspberry Pi Ubuntu and Evolution

I have been using a Raspberry Pi 4 running Ubuntu as my desktop for almost a year now. I don’t use it for anything too heavy and it has been adequate. But just adequate. I started doing a bit of coding and became more and more frustrated with performance and instability. At first I blamed the Google Chrome browser, a known memory hog. I was seeing 80% of my memory used (I have 4 GB) and that seemed to be at the root of the problem. But I noticed lots of cycles and memory were being taken up by some built in calendar application. It seems this is part of the Ubuntu Evolution email / calendar default application. it also seems like it is difficult to remove (come on, Ubuntu). I did finally find a good way to remove Evolution and since then, memory use is half of what it was and performance is noticeably better.
