Yes, mainly because it is roughly 1/3-rd of the data to process. (read compress

The viewer side desktop should be capable of displaying the colordepth. In most
situations, the same or a higher colordept should do.

You should search the mail archive for both vnc and tight-vnc (and optionally
other vnc variants) for the tool 'Cadence'. I've never seen or used the tool but
a remark of both Cadence and vnc makes me itchy, I recal by head that this
cadence is a verry bad behaving X11 application.

For the window manager, in vnc it is similar to at the console or at any other
X11-server. Between twm and cde, I can say that cde is a lot larger and hence
uses a lot more resources (memory, cpu etc). I recall that te t in twm is for
tiny, that sould say something...
