That file thing is a bit strange indeed, I hope there's some solution to that.

The problem is finding someone with some expertise of the Windows port of sqlite.

BTW: As your data is already in an sqllite DB, rather than copying it all from the into this mode=memory DB(*), why not just open connections to the existing db file from each of the threads using the uri-form connect string + the cache=shared modifier and see how the performance pans out.

(*especially as it seems these involve IO anyway.)
