Mongo is running with --nssize=2 --smallfiles

I create a new database with 7 documents in total stored within 3 collections - total data size is 1.6kb (KILObytes)

I look in /data/db and the database has already spawned a 32mb dbname.1 file - how could it think that it already filled the 16mb dbname.0 with so little data??

By this system storing 1.6kb of data takes 50mb of disk space (including ns file)!
