nxagent - 2:126.96.36.199-3+deb10u2
NX is a software suite which implements very efficient
compression of the X11 protocol. This increases performance when
using X applications over a network, especially a slow one.
nxagent is a nested Xserver providing NX transport of X sessions. The
application is based on the well known Xnest "nested" server. nxagent,
like Xnest, is an X server for its own clients, and at the same time, an
X client for a system's local X server.
The main scope of nxagent is to eliminate X round-trips or transform
them into asynchronous replies. nxagent works together with nxproxy.
nxproxy itself does not make any effort to minimize round-trips
by itself, this is demanded of nxagent.
Being an X server, nxagent is able to resolve all the property/atoms related
requests locally, ensuring that the most common source of round-trips are
nearly reduced to zero.
