Before revision:  We demonstrate AutoPerf's generality against three different types of performance regressions : (i) true sharing cache contention, (ii) false sharing cache contention, and (iii) NUMA latencies across 15 real world performance regressions and 7 open source programs.
After revision:  We demonstrate AutoPerf's generality and efficacy against 3 types of performance regressions : (i) true sharing cache contention, (ii) false sharing cache contention, and (iii) NUMA latencies across 15 real world performance regressions and 7 open source programs.
