I am setting up new SQL2016 Failover Clusters and I have noticed something that concerns me. I am working with Identical Setup Windows Server 2012R2 and SQL2016/SQL2012 with latest SP/CU on the same Virtual hosts and Identical network and disk setup. When I run TPC-C benchmarks against SQL 2016 I get about 1/6 the performance versus SQL2012 or SQL2014. I have tried compatability modes and changing the Cardinality Estimator to legacy mode. Does anyone have any idea what I might be overlooking? Has anyone else seen similar results?
