RE: [Ifile-dev] Re: performance improvements

[Paul Chambers]

Excuse me for being dense, but why the interest in moving the databases
between machines?

I would rather see performance optimization for the machine it is
running on, with a tool to export/import the native format to an
interchange format if and when the database needed to be moved across
architectures. Don't pay a constant performance penalty for a relatively
infrequent operation.
