HSQLdb (formerly known as Hypersonic SQL) and Apache Derbi (formerly 
knows as cloudscape DB) are two Pure Java databases, which are free and 
open source, and at least the first can run "in memory" in the JVM. As 
for faster performing ? I think you'd be hard pressed to find something 
better performing then MySQL and Postgres. Might want to try firebird, 
though I wouldn't get your hopes up.

I can't really see how it could be, and my experience indeed shows the

I'm not sure why do they think that, and I haven't read the entire 
article yet, but I doubt you'd get better performance from an internal 
DB then from a standalone highly optimized full RDBMs.
