I read that thread, but to be honest my eyes began glazing over.

That doesn't mean I don't care how well my office performs when a half-dozen people squeeze into it and try to get work done (which happened multiple times today...). Emacs regularly reacts too slowly for me when I use it in ordinary interaction, and I'd rather not see it get significantly slower. > As a data point, my 1.5 year old machine is about 150% faster (per core) > than its predecessor. My desktop uses a circa 2010 design and is no doubt significantly slower than your machine. No doubt that partly explains why I'm more sensitive about performance issues.
