Shameless plug but I cover a lot of lower level network and hardware effects for web developers in this book: https://unop.uk/book/ https://unop.uk/book/ It's mainly aimed at people interested in ASP.NET Core but there are a lot of general performance tips in there. I have a EEE background and I think understanding things down to the transistor level can really help you write better software. BTW Gary's WAT video is great fun if you haven't seen it.
