I have an application that loads 70 files of data in the legacy VTK format. 35 files contain scalar data, and 35 files contain vector data. The scalar files are around 4MB per file, and the vector files around 12MB.<div>However, loading all scalar files (with a vtkStructuredPointsReade) takes around 12 seconds, loading all vector files takes around 65 seconds. That's more than 5 times slower, while the files are only 3 times larger.</div>
<div><br></div><div>Is there a explanation for this difference in speed, and is there a way to increase the loading speed of those vector files? Would converting (all) files to a different format help with the loading time? Waiting 77 seconds before the data is loaded is a bit much.</div>
