Is reverse proxy worth it if website requires login?

Considering a website that requires user authentication, all pages have a "welcome username" string that is different for each user (like most of the websites these days)

The application is caching different page components and sets correct last-modified headers also static content is served by a different machine using nginx.

I think a reverse proxy in this case will slow down the website, is this assumption wrong and I'm missing somethi开发者_StackOverflow社区ng here, could the reverse proxy still improve performance?

You could serve your custom content ("Hello [user]") via json/javascript. In this manner, the load on the dynamic part of your server is simple - "What's my username?" rather then "Customise the homepage for user x".
