zlib compression in vtkMPIMoveData is slowing client-server rendering
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
zlib compression in vtkMPIMoveData is slowing down data delivery considerably. Following is a timer log for can.ex2. Possible solution would be to compress only when data size is beyond a threshold.
===client==== Still Render, 1.21436 seconds Execute vtkMPIMoveData id: 674, 1.19688 seconds Zlib uncompress, 0.016727 seconds
===server==== Execute vtkMPIMoveData id: 674, 1.1723 seconds Dataserver sending to client, 1.17105 seconds Zlib compress, 1.16047 seconds
