That's to be expected.
Setting journal-sync to false means transactions aren't synched at commit/rollback - they're just written to the OS buffers and the OS lazily writes them.
So you get performance at the expense of reliability.
With AIO you get performance with no reliability hit (that's the theory anyway)
