Derby does have an inexplicable 8-12 second wait when creating or 
opening a database where HSQLDB has no noticeable wait, which doesn't 
hurt on a server but on a desktop client it's a bit of a problem.  It 
really makes our unit tests grind too, since we use a fresh database for 
each test case.

But that being said, at runtime (which is normally what matters) we 
haven't encountered any noticeable slowdown using Derby over HSQLDB.

Maybe someone has some quantitative figures though, instead of these 
qualitative experiences.
