Hi Pavel,<div><br></div><div>I've changed it over to use a stateless session and I'm seeing the same behavior. I've done some debugging and it seems to be very slow loading up the SessionConfiguration due to all of the loading that happens in ChainedProperties. </div>

load binary compiled serialized package from disk. You can find it in<br>
documentation.<br>
Also consider using stateless session. Do you really need stateful session?<br>
