memory when using default_batch_fetch_size
Description
As since NH3+ setting the default_batch_fetch_size to something has very bad impact on memory as soon the SessionFactory is created. I'm using 3 sessionfactories in an web app (I'm accessing 3 db's). It uses 250MB without the setting but 750MB (default_batch_fetch_size=16) with the setting. When I switch back to 2.1.2 the problem is gone. My webserver recycles because the private memory is reached!
