Kevin Sutter commented on OPENJPA-370:
--------------------------------------
Thanks, Patrick, for the additional detail. Now I understand your concern.
And, I take that your profiling has shown that the performance degradation is
due to the changes introduced by this Issue? Can you share any more details?
Thanks.
So, we're in kind of a quandary... Do we cut the 1.0.1 release with this
change which makes LoadFetchGroups functional, or do we remove this change to
get the performance back up?
I'm surprised that we haven't detected a performance problem since we
introduced this change. I will check on that as well.
Thanks,
Kevin
