I've found an interesting resource https://developers.google.com/speed/docs/best-practices/rules_intro and here are some tips I've found interesting and useful in In-Portal:
https://developers.google.com/speed/docs/best-practices/rtt#PutStylesBeforeScripts (see "not_optimal_page_loading.png" attachment, lots of violet blocking requests)
- load stylesheet files before javascript files
- put any inline javascript after loading all of them
- don't serve cookies long with stylesheet and javascript files
- use jpegtran and similar tools to remove useless (for browser) information from images used on websites (including admin console)
- use efficient CSS selectors - selectors that not only work, but are processed faster by browser then other selectors, but work the same
Surely there is more to that document, that I was able to discover.
