That does the trick!!! With three packet tables with optimized sizes I now achieved to receive a file of size 30M within 14s. Unfortunately may previous mentioned ZIP-comparison numbers were wrong: the simple zip'ing takes 42s resulting in a 23M file. But with this approach and considering to have with the hdf the data accessible in a improved manner it looks promising. Tomorrow I will have to maintain additionally a packet table keeping references to the arrays in the original order ... Thanks for every hint! Johannes Stamminger
