Unfortunately, you are not the first, and no doubt the last either, to
report performance issues using the Base with integrated hsqldb. The
problem is not hsqldb, which actually on its own performs quite well,
but the manner in which Base loads everything into memory to be able to
work.

You could try issuing a SHUTDOWN COMPACT command from the Tools > SQL
dialog, then saving and closing your ODB file before re-opening it again.
