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".
