No, it does a random access on a 256 MB file for each query. Since 100 MB of 
memory do not allow to cache the file, the disk will go quite crazy. If 
you're sharing less than 1 GB, I would recommend to decrease the database 
size (will require recompilation, edit src/include/config.h, read comment, 
then you must run gnunet-check, you may also want to remove 
~/.gnunet/database* first). If you decrease the database by a factor of 8, 
you can share 1 GB of data and the database will be 32 MB large, small enough 
to be cached entirely by Linux whenever other applications don't need the 
memory.

What is gnunetwatch?
