Re: [eclipselink-users] Interpreting PerformanceProfiler output

[James Sutherland <jamesssss@xxxxxxxxx>]

The unqualified block seem to be a UOW regsiterObject() call (could be
EntityManager persist() or merge()).  What did you execute to get the
output?  Did you execute the read query, then call a register?

Potentially is could be when a read query is executed in the UOW it profiles
the query and register separately, I don't think the time is included in the
query profile.
