> Our performance tests show regression in read-heavy scenarios with the default settings. Even with the JBEAP-1740 performance fix applied, the test progress is very different from the EAP6 tests.

> While changing max-unreplicated-interval to 0 in EAP 6 tests may change the test progress to be similar to the EAP 7 tests, performance results with EAP7 using the *default settings* have to be comparable with the results from EAP6.
