Azure 计算单元 (ACU)Azure compute unit (ACU)

Azure 计算单位 (ACU) 这一概念提供一种比较 Azure SKU 的计算 (CPU) 性能的方法。The concept of the Azure Compute Unit (ACU) provides a way of comparing compute (CPU) performance across Azure SKUs. 这有助于轻松确定最有可能满足性能需求的 SKU。This will help you easily identify which SKU is most likely to satisfy your performance needs. ACU 目前在小型 (Standard_A1) VM 上标准为 100,而所有其他 SKU 表示 SKU 在运行标准基准测试时大约可以有多快。ACU is currently standardized on a Small (Standard_A1) VM being 100 and all other SKUs then represent approximately how much faster that SKU can run a standard benchmark.

ACU 只是一种规则。The ACU is only a guideline. 工作负荷的结果可能会有所不同。The results for your workload may vary.
