However, retrieving even the simplest of results from memory should be faster than opening a file on disk, preparing a db handle, querying, and then returning the result.

I don't think SQLite uses sockets. memcached does use socket. That might explain the difference, maybe benchmark against a database which uses sockets.

Or maybe opening "foo.txt" is skewing the results (unlikely, but it could happen)

At worst, it should be about the same, not 30% worse

I literally don't know about that, you might wish to ask the mailing list (amusing story about that).
