[Paraview] Slow loading data with geometry

[wturner]

Hi Cory,

for the geometry VTM (attached) looks to be ASCII and the VTP is base64 
(random attached, but different VTP's have different lengths of base64 
stuff).
for the events, they are stored as .heprep (again, attached) then loaded 
in using a GeantToVTK plugin to a Multi-block Dataset.

I didnt build from source, just using the binaries on SL6.

Thanks,
WT
