More on FSB:
•Pitfalls of benchmarking: if done with an application with low F would grossly overestimate performance.
•Actual memory performances very different due to memory latency etc.
•Example: for 1.5 Ghz Intel processors the load latencies for L1 and L2 are about 2 and 6 clock cycles respectively.
•These latencies increase drastically once main memory is accessed due to bus limitations.
•To overcome these problems techniques such as prefetch, data restructuring (more later) should be used.
