Yeah this is definitely true for Marginalia. It does exactly what it needs to do to serve the page and very little else. There's also no superfluous scripts in the frontend, no session cookie, no user tracking. That stuff does add up. Many applications do so many redundant calculations it's almost absurd. Professionally I've seen applications do enormous ORM lookups that fetch thousands of objects, stick them into a hash table by some key, and pick one value and compare against some parameter; and then do this operation in four different places in processing a single request. Gee I wonder why we have 800ms page loads...
