Measuring Cache and Memory Latency and CPU to Memory Bandwidth
With today’s computer architecture industry focused on clock speed and processing core count, it is easy to lose sight in other factors that play important roles in overall system performance. Memory latency and bandwidth are two major factors of performance. These two key aspects of system architecture can be broken up into processor cache and system memory. The open source LMBench Benchmarking suite provides utilities to accurately measure latency and bandwidth.
