heavyweight adj.
[common] High-overhead; [baroque]; code-intensive; featureful, but costly. Esp. 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 utilization, 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]. Oppose `lightweight'. Usage: now borders on techspeak, especially in the compound `heavyweight process'.
