AFAICT, the slowdowns affect GTK+ apps much more than Qt apps.  I know that 
the last time I tested running apps over ssh -X on a slow pipe, firefox was 
unusable while konqueror worked reasonably well.  Modern application/widget 
programmers are just not optimizing stuff for non-local connections, since so 
few people do that these days.

If you meant "vncserver", then that's exactly what it's supposed to do.  This 
is by design, as providing a new virtual Display is easier than 
screen-scraping an existing Display and using XTest to manipulate it.  Since 
people like to manipulate existing Displays and the X clients on them, they 
invented x11vnc (and xmove, but xmove, while a neat idea, is too @#$%^ing 
slow.)

Wow.  It's been a while since I messed with NX, but something is wrong here.  
x11vnc on Fedora 7 (no x11vnc RPM there, oddly enough) required installing 
all the X development packages, then compiling from the tarball.  About 30 
minutes IIRC.

Interesting.  I'll have to check out that extension later.

I don't think -C helped that much when I tried it, but I didn't add -c 
blowfish .
