Summary0009409: Use zlib compression when transferring geometry to client
DescriptionIn a recent email to the ParaView developer mailing list, Burlen Loring suggested zlib compressing the geometry sent from server to client. That is an excellent idea.

One way to implement the compression is to use the XML writers/readers to marshal/unmarshal the objects. However, it might be much easier to continue to use the legacy writers/readers and simply compress byte array before sending it.
Additional InformationEfficient remote interactivity is paramount to the near-term needs for large scale visualization at Sandia. Thus, I place a high priority for implementing this for ParaView 3.8.

zlib compression is now used when delivering geometry by default.
