try H2 internal connection pool instead of UnpooledConnectionProvider
#1 Updated by Eric Faulhaber almost 8 years ago
I read in the H2 documentation that the H2 internal connection pool should be significantly faster for embedded databases than using the
DriverManager directly, which is what
UnpooledConnectionProvider does. I'm not sure if this also applies to in-memory databases, but it's probably worth a try -- the effort to implement this is not high.
