= H =
[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'.
