Intel® Memory Latency Checker (Intel® MLC) is a tool used to measure memory latencies and b/w, and how they change with increasing load on the system. So, measuring these latencies and b/w is important to establish a baseline for the system under test, and for performance analysis. Besides latency, bandwidth (b/w) also plays a big role in determining performance. In a multi-socket system where Non-Uniform Memory Access (NUMA) is enabled, local memory latencies and cross-socket memory latencies will vary significantly.
