Hi
I am totally new to hdf5. Lately, I replicated a database to hdf5 format and 
created API in C for it.But when I read huge compound array from my database 
first time, it is slower than original API (also in C) which is reading same 
info by parsing from a hierarchical text  database. When I run my software 
second time to do same thing, time performance gets little bit better, but 
still slower than original one. So my question is:Is it an expected behaviour? 


_hdf5_status = H5Dread( _hdf5_dataset_id, _hdf5_memtype, H5S_ALL, H5S_ALL, 
H5P_DEFAULT, tempC);
tempC is dynamically allocated compound array.
