Hi, I tried with nioMapped on a Mac OSX. I have a proc that needs to do a lot of inserts and nioMapped is about 20% faster (if not more). I did not test any select to compare the speed, but it seems at least as responsive.
There is a problem though: I could not connect to a previous database created with jdbc:h2:.. using jdbc:h2:nioMapped:... Is it normal? Is so, do you think that a future version will take care to make the database compatible? Thank you for this very fast database.

You are right, I made a mistake... I will fix it.
