Rick Hillegas commented on DERBY-6533:
--------------------------------------

Here are the results of today's 4 hour run on the 8 core machine. No timeouts. No errors.

STATISTICS OF OPERATIONS DONE
-----------------------------



Start time = 2014-06-04 13:55:08.54
End time = 2014-06-04 17:55:08.547
Duration = 240 minutes



SUCCESSFUL: 
	Number of INSERTS = 1763109
	Number of UPDATES = 869230
	Number of DELETES = 869533
	Number of SELECTS = 77954

FAILED: 
	Number of failed INSERTS = 0
	Number of failed UPDATES = 843754
	Number of failed DELETES = 845147
	Number of failed SELECTS = 0

  Note that this may not be the same as the server side connections made
   to the database especially if connection pooling is employed

NOTE: Failing operations could be because of locking issue that are
directly related to the application logic.  They are not necessarily bugs.

Max sequence counter peeked at = 1798700


Last total memory = 6278873088, last free memory = 5021092824 as measured at Wed Jun 04 17:51:52

> Right now NsTest produces an enormous log file. This may be useful for tracking down
some errors. However, this can also make it hard to find the signal in the noise. It would
be good to turn off the chatty diagnostics which report the result of every insert, update,
delete, and select. A summary at the end may be good enough, including a summary of the number
of times each kind of error (SQLState) was seen. While I'm in there, I plan to make other
smallish changes.
