heavyweight
     
        High-overhead; {baroque}; code-intensive; featureful, but
        costly.  Especially used of communication protocols, language
        designs, and any sort of implementation in which maximum
        generality and/or ease of implementation has been pushed at
        the expense of mundane considerations such as speed, memory
        use and startup time.  {Emacs} is a heavyweight editor; {X} is
        an *extremely* heavyweight window system.  This term isn't
        pejorative, but one hacker's heavyweight is another's
        {elephantine} and a third's monstrosity.
     
        Opposite: "lightweight".  Usage: now borders on technical
        especially in the compound "heavyweight process".
