[Paraview] ParaView Memory Usage

[Hedieh Ebrahimi]

Hi Utkarsh,

I am opening h5 files using PFlotran HDF5 reader to open my files which are
result of PFlotran simulation.

ParaView uses more memory when I load a big file with lots of arrays and
just select one array in reader´s properties panel than when I have
manually splitted my big file using python and then opening it in the same
reader and selecting the same array.

Is there anyway to fix this bug? This could make everything much faster.

Thanks in Advance
