The menu I want to add/remove elements in is the menu generated from X-theme in settings (Buddypress navbar menu)
(Youzer menus I have managed to change. )
Regarding speed, I have read this article before, and also uses W3 total cache. But I have no CDN activated. If i search the net, X seems to deliver first paint in about 4 seconds in average in every site I find test results. Im my opinion this is not good enough. If I compare other theme results theu deliver from 1,5 to 5 seconds. This article does'nt explain/shows any way to make a faster X-theme.
