To resolve 3 strings we have to download 26 MB of data.

Getting rid of filelists seems like a bad idea because they are so
useful.  Implementing them better on the other hand ...

At the moment they are stored in a sqlite database which is bzip2
compressed.  The filelists DB for Fedora 18 is 26 MB compressed or 143 MB

The sqlite database just stores basically the strings as-is.  There
are some structures which are better for storing strings that have a
lot of common prefixes, such as tries and suffix trees.
