Hmm, don't think I made a chatter in FLTK.
I did make a telnet based chat:

and a browser based web chat:

Perhaps you're thinking of a dumb terminal emulator
that lets one type commands that run in a shell and
see the stdout/err of the commands in an FLTK window:
http://seriss.com/people/erco/fltk/#SimpleTerminal
In that case I did use Fl_Text_Editor.
I haven't really seen cpu issues with it, but I suppose
it depends how you make use of it.
I see the subject of this thread being URLs in text,
which might mean the FLTK html widget is involved.
That may have speed issues, as I think it has to re-parse
everything when changes are made.
If I needed a chat program that allowed URLs to be
automatically clickable, hmm, yeah, might have to customize
Fl_Text_* to do that.
