Chris Riccomini commented on SAMZA-544:
---------------------------------------
It just occurred to me that we should move this test to Zopkio, rather than
deleting it. This will solve our silly memory problems. The test is still
valuable, since it lets us test container performance without Kafka.
> TestSamzaContainerPerformance throws OOM occasionally
