[Paraview] What is the performance bottleneck in ParaViewWeb?

David,

Did you ParaView come from the openFOAM distribution? If so I wonder what
differences there are in the compilation settings and patch sets for
openFOAM's packaged ParaView and the binaries from Kitware. You might try
installing the 4.1 binary from Kitware in a different location and
comparing that to what you have.

cheers
