48-Hour Benchmark Results

The 48-Hour Benchmark has been used to evaluate the performance of a few systems. The 48-Hour Benchmark utilizes the following workloads with and without Cache Allocation Technology:

• Caterpillar - The Caterpillar benchmark measures the execution time variation of a memory test workload. The performance of the workload is impacted by cache misses. Using Cache Allocation Technology improves application performance by assigning CPU affinity to cache ways, which can be dedicated to real-time applications.

• Cyclictest Workload - Cyclictest is most commonly used for benchmarking real-time (RT) systems. It is one of the most frequently used tools for evaluating the relative performance of an RT. Cyclictest accurately and repeatedly measures the difference between a thread’s intended wake-up time and the time at which it actually wakes up to provide statistics about the system’s latency. It can measure latency in real-time systems caused by the hardware, the firmware, and the operating system.

The data shown below demonstrates the advantage of Cache Allocation Technology when executing real-time workloads.
