Here some numbers. Data generated as
source = vtkImageSinusoidSource() source.SetWholeExtent(0,512,0,512,0,512) source.Update() is saved as: VTI uncompressed, VTI compressed, XDMF. The sizes on disk are, respecitvely 1080046108,105356654 and 1080047720 (h5 part). The files are then read back. It takes about 1s, 4s and *100s* respectively. Writing seems reasonable, but there is clearly a serious issue with the Xdmf reader, because if I read the data in the h5 file using python tables it takes about 4s. I will be glad to hear any suggestions how to locate the problem.
