[Paraview] How is builtin different from localhost?

[Biao She]

Thanks for your reply.
I have another question though. You said the two processes communicated via
TCP sockets. What do they actually transfer? The final rendered image? The
vtk class methods calls? Or both?
I also have tested the pvserver on a remote computer, and I connected to the
server with 100 M network. I am wondering if the network speed is good
enough for paraveiw? In other words, no huge display delay because of
network?
Thanks.
