Maybe if you set "PRAGMA synchronous=OFF" the performance would be nearly as good when going to disk as it is when using a RAM disk. With "PRAGMA synchronous=OFF", your database can become corrupt if you take an OS crash or power failure in the middle of an update, but I gather you really don't care about that. -- D.
