I think (not verified scientifically) that it is due to the forum 
software (DFeed) being written in D and hence compiled, vs. a lot 
of other forum software that may be written in interpreted 
languages. I too have noticed its speed. Plus of course, all the 
points that others have said about a lot of extra stuff on other 
sites, like 2 MB pages, JS, video, ads, trackers, etc. I also 
read somewhere that DFeed is open source, so anyone who wants to 
study it, can do so. If I ever setup a forum, I'll try using 
DFeed for it.
