Should read: "I may extract this test with some small effort", of
course ;-)

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!
