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

Here is the output from today's 4 hours run on the 8 core machine. Summary: no errors, no
timeouts.

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



Start time = 2014-06-03 17:27:46.528
End time = 2014-06-03 21:27:46.538
Duration = 240 minutes



SUCCESSFUL: 
	Number of INSERTS = 1725420
	Number of UPDATES = 848622
	Number of DELETES = 848954
	Number of SELECTS = 76690

FAILED: 
	Number of failed INSERTS = 0
	Number of failed UPDATES = 826673
	Number of failed DELETES = 824280
	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 = 1756584


Last total memory = 6255804416, last free memory = 4635589648 as measured at Tue Jun 03 21:24:32

> 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.
