Store data in hierarchy, does it impact the performance?

Hi All,

I really need your help or idea, do I need to store data in hierarchy if I want to use HDF5? When I do a small benchmark, the performance of the file decrease when the data store directly in a dataset (after a 'root' group), rather than in a hierarchical way, Is there any reason behind that result?

Please, really need the reason of this question.

Thank you.

Regards,
Elisa MS

  Hmm, I don't have any good reason why this should be so. Do you have a small benchmark that demonstrates the issue?
