Complete desktops currently are still faster than single-application
windows via NX. 

Complete desktops benefit from NX-compression and -caching of X traffic 
as well as from 99% roundtrip suppression.

Single application windows benefit from  NX-compression and -caching of 
X traffic, but still suffer from 100% roundtrip slowdown. 

Single application windows via NX are still faster, though, than single 
application windows via plain vanilla X, because NX compression is better 
than ZLIB ("ssh -C") compression and because the NX caching of traffic
has some very good effect too.

But the real speed gain on slow/lo-bandwidth *as well as fast/hi-bandwidth
links only comes if you combine it all with roundtrip suppression.

Roundtrip suppression will come once the nxagent component of NX has
"rootless window" mode enabled, but it is not yet stable.
