I was trying to get our GGC application running on USB and it turned out
that HypersonicSQL is very slow on shutdown (over 1.5 minutes with just
USDA database). So I was trying different databases with our aplication
and I found one that will replace our current one... It's called H2
(http://www.h2database.com/). I tried some others including Mckoi (which
failed totally) and Apache's Derby (I needed to hack hibernate to use
it, eventhough it should be supported). H2 is faster than Derby about
100% when init of database, little bit 20% on running, and it needs less
files and space (8,7Mb, 14 files) than Derby (15 Mb, 110 files).
So with next released version you should have H2 database included.
If you are user, then this will be packed in you next release archive.
If you are developer, this means you need to update ggc-support tree.
