MongoDb networking overhead when using official C # driver to store small files

GridFs has a default size of 256kb, but if I store many small 6kb files, would I take the overhead of a 250kb discspace pr reserved but unused file, or does GridFs pack small files into the same chunk? (I know there is some additional metadata overhead).

The same question was asked and answered by the mongodb-user group in google groups .



The last chunk of the GridFS file is as large as needed, so there is no overhead.

In your example, a 6kb file will be stored as a single 6kb block (plus metadata).
