I read that thread, but to be honest my eyes began glazing over. I'm 
sure I missed some points.

And most of the time, my office at work is empty. 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.

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.
