I haven't done any formal tests, but last week when running the 
'all.dem' X11 terminal still seemed noticeably faster than Qt terminal. 
  But it's an apples and oranges comparison really.  I can tell that 
imaging is pretty slow in Qt, but Qt is doing more.

I wouldn't classify X11 terminal as deprecated.  It serves a much wider 
base than several of the other terminals still retained.
