I have stopped inserting new blobs when my application showed a memory usage of 400 MB, whereas it's
usage is 5 MB right after startup, so I think it's fair to assume that it does not stop at a certain
point.

I both cases I am working on the same machine, it's only the DB thats different.
Pagesize on both DB's is 4096, Buffer is 2048 pages or 8192 KB.

There is no update of any blobs yet, whatever is loaded from file will result in a fresh insert.
What puzzles me even more is the consumtion of memory when saving to file.
