Hi Brian, I am observing very inconsistent behavior during our performance testing. I have a five-node VM based cluster and my average performance test result is 1.3 seconds for 10 threads. No issue with bringing down one or two nodes and re-execute performance testing. However, when I bring up a down node during the performance testing, all test cases were clocked at 7.7 seconds, a six times increase. When I re-executed the test cases after all five nodes are up a while, the test results are back down to 1.3 seconds. It seems like bringing up a node has a significant performance impact on the cluster itself. Does it make any sense? I can consistently reproduce this behavior. Thanks. -- Lei
