Hi,

Nothing specific, but:

I'd think the main difference here is probably Hibernate vs TopLink,
not GF vs JB. You might want to do cross-tests to narrow it down.
Honestly, with something this simple, I'd expect the difference to be
Hibernate default settings vs TopLink default settings.

If the performance with Hibernate in Glassfish still differs from
JBoss, compare the jdbc connection pool sizes in the two cases, last I
heard MySql did not benefit from too many parallel connections.
