Hi Thomas,

thanks for updating the info on Derby!

I believe the thrust of the slides in JavaOne/Jazoon 2007 was twofold:
a) Derby performance is comparable to other open source databases, and
b) no size fits all, viz. both PostGreSQL and MySQL was shown faster
than Derby in some use cases, Derby faster in others. So pretty benign
claims, if you ask me. No claim such as "database x is slow". I would
still encourage people to do their own benchmarking when making
decisions on performance.
