Re: [eclipselink-users] Slow Mapping
|
Hi James,
i've enabled FINEST logging and additional messages has added:
FINEST Register the existing object 50006000
this registry is added per each Object. does this mean is caching the
object in every query?
no more native queries has been executed.
Thanks,
